ARM load DSP's firmware failed

Shaoguo Chai

hi all,

we use 6AL1.1 sdk now and when arm load DSP's firmware, it will appear errors as follows:

[   12.333007] remoteproc2: bad phdr da 0x800000 mem 0x1000
[   12.333012] remoteproc2: Failed to load program segments: -22
[   12.368324] omap_hwmod: mmu1_dsp1: _wait_target_disable failed
[   12.380709] omap_hwmod: mmu0_dsp1: _wait_target_disable failed
[   12.386642] remoteproc2: rproc_boot() failed -22

the address 0x800000 is DSP1's L2SRAM.

we use 6AJ1.3 sdk to load same firmware, it not exist this problem.

we compare the kernel in 6AJ1.3(kernrl-3.8) and 6AL1.1(kernel-3.14), and found the file arch/arm/mach-omap2/remoteproc.c is not different,

In kernel-3.8, it do same work for L2SRAM, but In kernel-3.14, it not do.

how could I resolve this problem? please give me same idea, thand you very mach.

best regards.

Hello,

Can you give more information? Which board is it, is it custom, are you using Android?
Also can you explain what you are trying to do?

hi,

Now we use VAYU evm XC5777X CPU BOARD(rev E1) and run android sdk 6AL1.1 on it.

we want to use DSP's internal EDMA to move the data from external DDR to DSP's internal L2SRAM.

we allocate a segment from the L2SRAM, but the kernel could not identify this segment when it load the DSP's firmware.
