I want to startup A core and R core in our board. but through A core starting up, there is something wrong and can not start up successfully. The start up log as following:

And I found that A core can start up successfully if I removed j7-main-r5f0_0-fw .  And when there is j7-main-r5f0_0-fw in SD card, A core can not start up successfully, R core runs OK.

Please help me to analysis why my A core can not start up successfully when there is j7-main-r5f0_0-fw in SD card.

Thanks a lot.
