66AK2H14: Linux freezes when it should reboot

Hi,

Which kernel is this? Are you using EVMK2H or is this a custom board?

Best Regards,
Yordan

Hi,

Kernel version is 4.19.61 and the board is custom one.

Hi,

Could you transition to Processor SDK Linux: kernel 4.19.38+?
If you wish to continue using 4.19.61, could you at least send me the logs of the linux getting stuck on reboot?

Best Regards,
Yordan

Hi,

Here is the log from kernel boot to kernel freeze.

Downgrading the kernel could be on option for test purposes, but it's not an option on the long run.

Starting kernel ...

Hi,

I have an update to this case.

This patch made the reboot work:

diff --git a/drivers/clk/clk.c b/drivers/clk/clk.c

index 5413ffa..24ecf08 100644

--- a/drivers/clk/clk.c

-       if (clk_core_is_enabled(core)) {

+       if (clk_core_is_enabled(core) && (0 != strcmp(core->name , "ddr3-1"))) {

                trace_clk_disable(core);

                if (core->ops->disable_unused)

                        core->ops->disable_unused(core->hw);

I am now seeing if it's possible to make an equivalent change via device tree instead of a kernel source patch.
