TDA2SX: remote proc module would not installed in my custom board

Hi Liu Gan,

In the log, I don't see remoteproc module traces. If you do "lsmod", is remoteproc listed as loaded? Is the firmware present in /lib/firmware with the expected name?

Is the issue that the module is not being auto-loaded? If not, can you please give more information or traces on the remoteproc error you are seeing?

Regarding the firmware loading when remoteproc is built into the kernel image, you will need to also enable the firmware loader helper config options in order for it to fall back to the user helper when direct firmware load fails:

CONFIG_FW_LOADER_USER_HELPER=y

CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y

Thanks,

Angela

Hi Angela,

I have tried your suggestion that enable the
CONFIG_FW_LOADER_USER_HELPER=y  and
CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y
while build the remoteproc into the kernel zImage.

But still i cannot get the firmwares loaded.
This is the kernel startup log:

And also, i noticed the comment under config FW_LOADER_USER_HELPER_FALLBACK says:

I don't know what does that exactly mean. Does it say that the udev service don't support load firmware now?

Hi Angela,

Yes, the remoteproc module is still working fine.

I am studing the possibility build the remoteproc into the kernel image. Never mind.
