Failing to build kernel for mp157

Follows the instruction
I try to build kernel 5.15.x for stm32mp157d-dk2 and have git clone procedure as failed:

fatal: Resolve operation not in progress, we are not resuming.
/usr/bin/git tree is clean...

After these messages script trying to fetch another variant and it also failed:

USB hub not working

Hi, thanks for this great script/tool package.

I tried it with the default stable kernel, as well as torvalds, as well as directly with the ST linux kernel fork, and it works great in the sense, that the stm32mp157c dk2 board boots up correctly, internet and display works, but no USB devices are detected when plugged in. Can you please comment on this?

EDIT: I followed your guide here:

Ability to flash Artik 10 eMMc

Hi,

I was wondering if we will be able to flash your debian build onto the Artik 10 eMMc in the near future? My lab is a big fan of your work on the BeagleBone Black and we're interested in using the Artik 10, but we've had trouble reliably booting from SD cards in the past.

Thanks,
Will

Unable to boot v5.4 with rt patch

Hello, I am unable to boot linux kernel 5.4 with rt patch on STM32MP157-DK2 development board.

Steps to reproduce

  • checkout v5.4.x branch
  • select toolchain="gcc_arm_gnueabihf_10" in version.sh
  • uncomment rt in patch.sh

menuconfig

  • change kernel mode to PREEMPT_RT
  • set timer frequency to 1000 Hz

Booting does not continue and board is reset every 32 seconds by watchodog. Could you please provide any suggestion how to get any kernel running with rt patch? I do not insist on using 5.4, but i need rt.
Thanks
