kernel stuck on 'brd: module loaded' at boot.

Sometimes kernel would stuck on 'brd: module loaded' and FPGA stop booting, only reconnect power supply to make FPGA boot again to 'exit' this stuck.

​

The below picture shows how the kernel work in proper boot process.

In sometimes, it will stuck on 'brd: module loaded' and no anymore logs shows.

​

We made a change that we would loaded two .rbf from SDMMC two different partitions. We are invoking cff_from_sdmmc_env(); twice.

​Is that invoking cff_from_sdmmc_env(); twice lead this kernel stuck problem?

Any change we should make to support loading two .rbf from SDMMC two different partitions?

    Hi,

    Have you tried loading only one of the .rbf file to see if everything works correctly?

    Are you attempting to load both rbf files at the same time?
