services/os/freertos/source/portable/:
Fixed bad context switching leading to unpredictable behavior in this tricky case:
A Tick interrupt is triggered in vTaskDelayUntil while this function was preparing a task switching in a critical
section.
•
utils/libs/dsplib and services/dsp/dsplib: Fixed missing #include of dsp.h leading to compilation of
unoptimized generic functions:
trans_dsp16_complex_fft.c
trans_dsp16_complex_ifft.c
trans_dsp16_realcomplex_fft.c
trans_dsp32_realcomplex_fft.c
•
boards/uc3l_ek/uc3l_ek.h: Add signal connections on the WLESS connector.
•
utils/compiler.h: Fixed __count_leading_zeros intrinsic that is broken in IAR 3.30.1 and 3.30.2.
•
services/network/can: move drivers/canif/can.c-.h with example1&2.
•
drivers/usbb/_asf_v1/:
Fixed tricky bug when using the audio application: the pipes needs to be configured in DOUBLE_BANK,
otherwise some audio clicks may (will...) appear if the CPU needs sometimes to take more than 1 ms to
process an audio packet. This happens with the re-sampling algorithm V2 (+20% CPU needed compared to
V1).
•
drivers/twi/: fixed the "burst" of TWI master interrupts between the transmission of the last character and the
end of the frame, leading to unexpected CPU workload.
•
drivers/eic/eic.h: add defines missing from the system header files.
•
drivers/eic/example1/: port the example to the AT32UC3L-EK board.
•
drivers/pm/pm_uc3c.h, pm_uc3l.h: remove the pm_sleep() macro; create a pm_sleep() function in sleep.h.
•
drivers/scif/example3_uc3l/scif_example3.c: use the SLEEP() macro instead of pm_sleep().
•
drivers/eic/example1/eic_example1.c: Move the init and setting of the LED0 GPIO to one place.
•
applications/evk11xx_uc3b_virtual_com_port/: Make use of the STOP sleep mode rather than the STATIC
sleep mode. This fixes spurious VBUS transition interrupts that prevent the part from entering in the sleep
mode.
•
drivers/pm/sleep.h: new file to act as a stub on the PM sleep feature for the new sleepmgr service.
•
drivers/spi/spi.h, spi.c: changed the pba frequency variable type from 16-bit to 32-bit in order to avoid
overflows.
drivers/flashc/flashc.h, flashc.c: add void flashc_set_bus_freq(unsigned int cpu_f_hz) (and
flash_set_bus_freq() as an alias on the former) that sets the appropriate
flash wait state depending on the target CPU frequency.
drivers/flashcdw/flashcdw.h : add flash_set_bus_freq() as an alias to
flashcdw_set_flash_waitstate_and_readmode().
boards/evk1100/evk1100.h, boards/evk1101/evk1101.h, boards/evk1104/evk1104.h,
boards/evk1105/evk1105.h: Add oscillator definitions usable by the new clock service. These include frequency,
startup times and oscillator type for OSCn. BOARD_OSCn_HZ currently overlaps the existing FOSCn defines,
but the former has a better name and should eventually supersede the latter.
•
•
•
•
•
drivers/flashcdw/flash_example/flash_example.c: set the variable user_nvram_data as __no_init for IAR so
that the binary can be programmed through batchisp and a bootloader.
•
drivers/usbb/_asf_v1: fixed bad management of the USB SOF interrupt, leading sometimes to a deadlock in
the timeout detection.
•
services/crypto/polarssl: udpate from version 0.12.1 to 0.13.1.
Features
Added option parsing for host and port selection to ssl_client2
Added support for GeneralizedTime in X509 parsing
Added cert_app program to allow easy reading and printing of X509 certificates from file or SSL connection.
Changes
Added const correctness for main code base
X509 signature algorithm determination is now in a function to allow easy future expansion
Changed symmetric cipher functions to identical interface (returning int result values)
Changed ARC4 to use seperate input/output buffer
Added reset function for HMAC context as speed-up for specific use-cases
Bug fixes
Fixed bug resulting in failure to send the last certificate in the chain in ssl_write_certificate() and
ssl_write_certificate_request() (found by fatbob)
Added small fixes for compiler warnings on a Mac (found by Frank de Brabander)
Fixed algorithmic bug in mpi_is_prime() (found by Smbat Tonoyan)
•
drivers/ast/example2/: add precautions as mentioned by the datasheet before entering the static sleep mode.
•
components/wifi/hd: Update H&D WIFI stack version from 2.1.1 to 2.3 :
Added features for this release
- Enhanced throughput
- Support for all EVK platforms for SPBFW_DOWNLOAD
- Allow static IP configuration in http demo
- TTCP Improvements
- Add support for SPI and SPB105 on EVK1104.
Fixed bugs:
- #133 Remove patched framework files included in release
- #156 connection manager starts even though no network is set
- #158 Scan command in GUI does not handle scan properly
- #179 HTTP server occasionally hangs on EVK1104
- #193 Potential HTTP server web page buffer overflow
- #196 Indicate that no WiFi card in GUI (if not present)
- #210 Trailing '?' characters not handled in URL queries (Safari/Opera Refresh bug).
Known bugs in this release (2.3)
- PSK generation is quite slow (on the order of 10 seconds) which manifests by the connect command
or the wl_connect() call taking around 10 seconds to complete when the network uses WPA/WPA2
pre-shared key.
- #203 ttcp error handling is not robust.
•
\drivers\usbb\_asf_v1/, services\usb\_asf_v1\class\hid\examples: Implement the USB Remote Wakeup
function. The HID Mouse example for the EVK1105 will wake up the HOST after a suspend when pressing
the center touch button of the kit.
•
\services\dsp\dsplib\generic\advanced\resampling: Improved the re-sampling algorithm. See the
documentation for more details \services\dsp\dsplib\resampling.pdf
