Tool/software: TI-RTOS
Hi all,
I use the ex02_messageq (DRA7XX_linux_elf) as an example to develop our application. It works well, but i remark after several "echo 58820000.ipu > unbind", and "echo 58820000.ipu > bind", in the "cd /sys/bus/platform/drivers/omap-rproc/" directory, when i make the "unbind" command, the board freezes without error message before. I can only make a hard reset.
This doesn't happen with the DSP firmware, only with the IPU firmware.
The number of "unbind"/"bind" cycles before crash are unpredictable.
I do a sleep between the "unbind" and the "bind" calls (up to 30 seconds).
I didn't modify the sources, except the "products.mak" file. Below, the configuration :
- Linux toolchain : ti-processor-sdk-linux-am57xx-evm-03.02.00.05
- BIOS : bios_6_46_01_38
- IPC : ipc_3_44_00_00
- XDC tools : xdctools_3_32_01_22_core
Have-you ever noticed this problem ?
Thank you for your help,
Olivier
