BSP Updates
Last
updated 02/22/10
Version 1.0
Serial Driver - case 30221
Removed extra stop bit that was
added between characters.
RTS was incorrectly being
deasserted for 1us before transmitting each character in RS485 mode.
The serial driver was incorrectly
using the CPU clock instead of the PLL for baud rate calculations.
Serial Driver - case 30049
serial_channel() now returns
minor as the channel number.
max_serial_ports() now uses
SERIAL_MAX rather than a hard coded value.
Serial Driver - case 29973
Fixed select()
implementation. We did not notify the
Treck stack about event changes. Added
ioctl option TCGETSIGCHANGE
USB
Driver
Updated ISR to call narm_read_reg
and narm_write_reg.
See latest API Reference for
updates to naUsbDevQueue about zero-length packets.
Wireless
Driver - case 29954
Updated Japanese channels for
802.11a
Wireless Driver
Fixed Cisco LEAP+WEP problem.
SPI
MMC Driver - case 28537
Fixes to SPI SD card driver to
address SD cards that do not respond for various reasons. (usually timeouts)
Version
1.1
Wireless Driver - case 30378
Fixed a problem that could cause
the WIEM9210 to sleep forever when an application changes duty cycle time on
the fly.
Fixed a problem with high packet
loss on the WiWM9210 using AES on b-g WLAN with protection enabled. Protection
mode allows a mix of B and G devices on
the same channel. It sends a CTS frame
(at a B rate) before every G frame. The
CTS frame tells B-only devices to stay off the air until the G frame is
complete. Protection mode is enabled by
the access point.
The problem our driver had was
that the CTS and the DATA frames are not in the same FIFO so the AP thought
they were invalid.
I2C
– case 30378
In customizeBootloader.c, we
overwrote the preconfigured GPIO line to check forced recovery status. This
would cause problems with I2C when run from flash. We now restore the GPIO line after checking
status.
Version
1.2
Error building NET+OS examples caused by missing
file. Added usbreg_def.h
Version
1.3
Fixed
a problem that would cause cout to stop working after any change to the dialog
was made. Case 30472
Changed
error checking code for BSP_GPIO_MUX_IOP_1_CAN_TXD and
BSP_GPIO_MUX_IOP_1_CAN_TXD in gpio.h to allow the 2nd alternative path, which
is a valid choice.
Added A band
channels (52, 56, 60, 64, 100, 104, 108, 112,116, 120, 124, 128, 132,
136, 140) to Japanese support.
Inside
the routine SetChannel() there was missing a setting of the
global_channel. Also added the file
mac_11j.o to Makefile.files (case 30569)
Version 1.4
Corrected
bug in NAMCWait which declared the timer handle to be static, thereby making it
possible for one thread to alter the variable while a second thread is using it
if both threads call into the function simultaneously.
Corrected
dialog behavior when APP_USE_NETWORK_TIME_PROTOCOL was TRUE and the primary
NVRAM SNTP address was 0.0.0.0. In that
case, the dialog never displayed the SNTP addresses and the operator would not
know they can update it at that time.
Fixed
incorrect size used in memcpy call in na_pton.
Version 1.5
Changed the receive gain table
for airoha chips.
Version 1.6
Implemented max gain control to
improve receive sensitivity.
Version 1.7
Fix to update the status when we
set the tx power. wln_get_status was not
returning the correct value for tx power.
Version 1.8
Fixed alignment issue in
MacBuffer that could cause Wi-Fi to crash when using Green Hills Tools.
Version 1.9
Fix for Ethernet receive stall
after a soft reset under heavy network load on ARM9 based chips. Case: 29694
Masked off interrupt for 9215 & 9210. This is needed since the hardware
doesn't handle heavy nesting of interrupts correctly. Case: 30345
Version 2.0
Implemented automatic adjustment
of the MAX AGC setting based on the receive strength of received frames.
Added firmware to enable the
second DC block HP bit in the transceiver.
Case 31462.
Version 2.1
Wireless
change that will wait for an ack after sending a probe_response before setting the tx state to idle.
Moved
min and max from fwtypes.h to minmax.h.
Define was causing build errors in C++ when using STL containers;
vector, map and string. Case 31471.
Version 2.2
Fixed problem where data overflow
error was occurring when the camry serial driver is flow controlled. When the
driver receives a XOFF it disables the transmitter, at this time it is unable
to send XOFF to the peer if need be, resulting in data overflow. Case: 31720
Updated readme files to match FIM
Application Kit H/W Reference.
Fixed Pll clk calls and updated
FIM code in onewire driver.
Updated FIM1 1WIRE and FIM0 UART
settings in bsp_iop.h for 9210 based platforms.
Fixed tx fifo underrun problem on
Connectcorewi9c_a.
FPGA file modified to utilize the
4096 byte depth of the recv fifo on Connectcorewi9c_a.
Fixed tx fifo reset problem on piper with new macassist code
Changed RF register 0xC's setting from 0xA3 to 0x2B for al7230
Limited Connectcorewi9p9215 operational max PSK/CCK power to 16dbm
Version 2.3
Moved naValidateIpv6Information
to nainet.c, renamed validateIpAddress to naValidateIpAddress, Updated API
Reference to add documentation to naValidateIpv6Information (case 31920)
Fixed a problem caused when there
was a low heap situation. (case 31856)
Changed the MAX_CODE_SIZE for the
WiEM, WiSP, WiEM9210, and CCWi9P9215 platforms to 3.5M. Note that all these platforms already have
the APP_MAX_SIZE_IN_FLASH set to 1856K. It's only natural that the MAX_CODE_SIZE (in
RAM) should be about double the SIZE_IN_FLASH due to the compression mechanism.
(case 31850)
Now checking the NVRAM backup
copy once, every time the unit comes up, to address the possibility of a
corrupted/stale backup sector. (case
31747)
Version
2.4
Updated file system interface
files to use an event flag instead of polling for the result to speed up file
transfer. (case 32017)
Version
2.5
Corrected a problem that could cause the I2C bus to hang if a reset is issued during active I2C communications. (case 32488)
Corrected a problem with size check when downloading backup image, and increased the backup image size in the ConnectME and ConnectME9210 to 512K. (case 32530)
Version
2.6
Set RTC device count to 0 in all ARM7, ns9750 and ns9210 based platforms. (case 32478)
Fixed a problem in the Ethernet
driver. The stack can sometimes send the
driver Ethernet packets that are spread out across more than one buffer. Apparently this happens a lot when using
IPSEC, and often 3 buffers are sent for a single packet. The driver was not
handling that well, and was getting confused.
Fixed customer reported rounding error
in NATimerPeriod2Raw. Error was about
(5/100) of one percent. (case 32430)
Fixed a memory leak in firmware download process. (case 32636)
Fixed problem with lock mechanism in
spimaster routine.
Version
2.7
Wireless
Updates
Now allow duty cycling while scanning.
Added LINKUP and LINKDOWN events. Updated
mwifimac for LINKUP and LINKDOWN event and added naWlnSetEvent for wpa to setup
linkup/linkdown event and startMultiScan for multiple channel mask scan.
Added naEkahauSetBatteryCallback prototype and
naEkahauSetStatusCallback API.
Added naWlnIsWirelessUp function to see whether
wireless is ready to transmit. We now make a call to naWlnIsWirelessUp if no
LINKUP event is received from the wifi driver to verify wifi is up before
sending ELP.
wlnNullFramePtrPS and wln_make_null_frame_ps
are added for background scans while staying associated. The unit sends a NULL frame with the
power-save bit set, so that the AP knows to buffer data for us. The unit sends
a NULL frame with the power-save bit clear when the scan is done.
Multipath problem fixed by resetting the transceiver before changing channels.
Fixed problem when in A band and in ad-hoc mode
that caused the unit to send out tons of RTS.
Fixed (Authentication type = WEP (802.1x))
Fixed a bug that was causing units to
occasionally skip association to the nearest AP because the MacTimer() wasn't
allowing enough time for a beacon to come in before it tried the next AP.
Version
2.8
Wireless
Updates
FPGA file updated, for connectcorewi9c_a
platform.
For Al2236 transceiver -
Config 7 = RSSI = default value
Original Setting: 0x05B688
New Recommended Setting: 0x0A8688
Note that the Airoha-recommended setting is dependent on the supply voltage:
0x05B688 for 2.8v, 0x0E4688 for 3.0v. The Piper WiEm voltage is actually around
2.88v, so the new value is consistent with the Airoha-recommended values
(between the two settings). (case 32800)
Serial Updates
The multiplexor that controls the output
enable for gpio[29] is being controlled the control register for gpio[28]. The
work around and limitation is that gpio[28] and gpio[29] must always be
configured to the same functional mode. (case 1284328)
Version
2.9
Wireless
Updates
Fixed problem that casued WiEM
9210 to crash when naPdSleep() was called. (case 33148)
Fixed problem where after waking up, the device did not detect it was
disassociated from its AP (case 33149)
Changed wireless driver so that when we fail EAP FAST authentication two times
in a row, we will delay 1 minute before trying again. We do this because
the EAP FAST negotiation is CPU intensive and interferes with other processes.
(case 33239)

files to handle this condition.
Updated API Reference (case 31873)
Version
1.3
Reworked a condition check in
PPPCloseInterface() that hits when close is called before open completes. This
check was incorrectly determining the interface state based on the current PPP
link level state.
Realport Updates
Last updated 05/26/09
Version
1.0
A pointer to the realport configuration
structure is passed as a parameter to a threads operation function which uses
that pointer to create another thread. If the configuration structure is a
local variable on the stack, we have a problem after the first call returns.
The solution is to save a copy of the configuration structure when
RealPortStartServer is called. Case
30485
SNMP
Updates
Last
updated 01/28/10
Version 1.0
Calls to function
naSnmpGetSysName() fail consistently with a return code of NA_SNMP_NO_MEMORY

SSL Updates
Last updated 08/26/09
Version
1.0
This change fixes a memory leak when
using naSslNgConnect. About 1500 bytes
of memory would be lost every time we made a client connection. (case 30656)
Version
1.1
Updated https_daemon function to start
tls_server_http with correct variable and thread. After the maximum tls_server_http threads
had been started, it sometimes reset incorrect connection info and restarted
the tls_server_http thread. Case 31362.
TCPIP
Updates
Last
updated 12/14/09
Version 1.0
Added support for IPv4 filtering.
Disabled interrupts
