SK-AM62A-LP: 'cryptodev': Cannot allocate memory

Other Parts Discussed in Thread: SK-AM62, AM62A7,

Hello

We are currently using SDK 9.01 and applying Falcon Mode.

And to boot from emmc, I set bootargs as below.

bootargs = "console=ttyS2,115200 root=/dev/mmcblk0p1 rw rootfstype=ext4";

However, after booting, loading the kernel module fails.

The log is as follows. Is there a solution?

root@am62axx-evm:/opt/edgeai-gst-apps# systemctl status systemd-modules-load.service
x systemd-modules-load.service - Load Kernel Modules

Hi, Liu

Thank you for your support.

But I still don't understand this phrase.

"the kernel Image load address in falcon boot is not 2MB aligned."

Can you please explain?

Regards,

Kim

Hi Kim,

The ARM64 kernel should be loaded at a 2MB aligned address.

In normal U-Boot boot flow, U-Boot loads and boots kernel image to $loadaddr which by default is 0x8200_0000, which is aligned at 2MB.

But in falcon boot flow, ATF boots kernel image to PRELOADED_BL33_BASE which by default is 0x8008_0000.

So the patch above is to modify tispl.its to load kernel to 0x8020_0000 which is aligned at 2MB, and modify ATF to boot kernel image at the same address.

I was able to incorporate the 2 mB alignment into my falcon build. It did resolve the problem with the vmap allocation. Thank you for your time on this issue.
