After I re-decompressed a spe demo, the firmware generated by directly compiling can realize the function of ivc echo normally. But after I enable can demo, ivc echo can’t work normally. Can’t these two functions be enabled at the same time?
I just modify follow code in the rt-aux-cpu-demo/soc/t18x/target_specific.mk,set this macro is 1
Hello,jachen
This problem may have something to do with the hardware I use. I can reproduce this problem with a baseboard designed by ourselves, but it is normal on the development board provided by nvidia. But our own baseboard does not provide the debug serial port of spe, so I cannot print log now
Hello, 674493271:
I cannot imagine why that’s related to hardware.
Maybe some pinmux changing, or dtb change?
Anyway, debug port is very helpful.
In addition,
<But our own baseboard does not provide the debug serial port of spe>
SPE shares the same UART port as kernel. Are you sure there no debug port in your carrier board? It’s better to add it, or BSP debug may be a hard job without UART.
