Hi Marek
Hi,
I tested the current U-Boot master branch
(22bfaa1f673ab5442dfb9778eea4c9a18dee42d0)
This patch is breaking the boot sequence on stm32mp157c-dk2.
Breaking it ... how ? What happens, hang ?
Here is the boot log :
U-Boot SPL 2022.04-00827-g22bfaa1f67 (Apr 21 2022 - 17:22:47 +0200)
RAM: DDR3-DDR3L 16bits 533000kHz
WDT: Started watchdog@5a002000 with servicing (32s timeout)
U-Boot 2022.04-00827-g22bfaa1f67 (Apr 21 2022 - 17:22:47 +0200)
CPU: STM32MP157CAC Rev.B
Model: STMicroelectronics STM32MP157C-DK2 Discovery Board
Board: stm32mp1 in basic mode (st,stm32mp157c-dk2)
Board: MB1272 Var2.0 Rev.C-01
DRAM: 512 MiB
Clocks:
- MPU : 0 MHz
- MCU : 0 MHz
- AXI : 0 MHz
- PER : 0 MHz
- DDR : 0 MHz
clock rate is 0
clock rate is 0
clock rate is 0
clock rate is 0
clock rate is 0
cloc
What worried me is that all clocks are set to 0 (MPU/MCU/AXI
....)...no direct link with the led-uclass update.
For information, if i comment the device_probe(dev) in
led_post_bind(), it avoid the hang.
Can you try applying the LED patch on top of 2022.04?
I made some clock changes recently, so it could be an interaction
with that.
Thanks for the tips, but unfortunately, i have the same issue when
applying this patch on top of v2022.04.
I am still investigating ..... ;-)
Maybe the clk_* in gpio_stm32 is the problem, is the gpio driver for mp1
probed by the time the led post_bind is called ? If not, maybe that's an
issue.
I'll have a look too.
Try this patch, does it "fix" it for you ?

If so, we need to figure out why.
