When updating from arm-trusted-firmware-v2.4-stm32mp-r1 to arm-trusted-firmware-v2.4-stm32mp-r2 I get PANIC on UART

I didn't change anything in the device tree just compiled the arm-trusted-firmware-v2.4-stm32mp-r2 instead of arm-trusted-firmware-v2.4-stm32mp-r1 and I get the following on UART:

PANIC at PC : 0x2ffcfd2b

What is different between the two versions?

@Community member​ 

I have tried using the Bootlin repo as an example and unfortunately, I still have issues. I even tried booting their image for the DK1 board but I am getting the same result. I feel like there is a fundamental problem somewhere with MCUs that are not stm32mp157x.

With the image I built I get:

NOTICE:  CPU: STM32MP153AAC Rev.B
NOTICE:  Model: STMicroelectronics custom STM32CubeMX board - openstlinux-5.10-dunfell-mp1-21-11-17
ERROR:   CMD13 failed after 5 retries
ERROR:   SDMMC1 init failed
PANIC at PC : 0x2ffe9b21

With the Bootlin image for stm32mp157a-dk1 I get: 

NOTICE:  CPU: STM32MP153AAC Rev.B
NOTICE:  Model: STMicroelectronics STM32MP157A-DK1 Discovery Board
ERROR:   CMD13 failed after 5 retries
ERROR:   SDMMC1 init failed

@Community member​ is it possible there is a problem with STM32MP153xxx MCU and DV3.1?

Hi @cfilipescu​ ,

Not I'm aware of.

Can you please provide the full TF-A DTS file.

I would like to review how you managed DK1 DTS adaptation to your mp153 device and check also the SDMMC1 related node, since the issue looks definitely is this area

Hi @cfilipescu​ ,

DTS you provided don't have &rcc node where you should have something like : 

.. 
 
	st,pkcs = <
		CLK_CKPER_DISABLED
		CLK_ETH_DISABLED
		CLK_SDMMC12_HCLK6
		CLK_STGEN_HSI
		CLK_USBPHY_DISABLED
		CLK_SPI2S1_DISABLED
		CLK_SPI2S23_DISABLED
		CLK_SPI45_DISABLED
		CLK_SPI6_DISABLED
		CLK_I2C46_DISABLED
		CLK_SDMMC3_DISABLED
		CLK_ADC_DISABLED
		CLK_CEC_DISABLED
		CLK_I2C12_DISABLED
		CLK_I2C35_DISABLED
		CLK_UART1_DISABLED
		CLK_UART24_DISABLED
		CLK_UART35_DISABLED
		CLK_UART6_DISABLED
		CLK_UART78_DISABLED
		CLK_SPDIF_DISABLED
		CLK_SAI1_DISABLED
		CLK_SAI2_DISABLED
		CLK_SAI3_DISABLED
		CLK_SAI4_DISABLED
		CLK_LPTIM1_DISABLED
		CLK_LPTIM23_DISABLED
		CLK_LPTIM45_DISABLED
	>;
 
...

For which you migth check status of CLK_SDMMC12_

And I don't see node &sdmmc1 in which you enable it : 

&sdmmc1{
	pinctrl-names = "default";
	pinctrl-0 = <&sdmmc1_pins_mx>;
	status = "okay";
 
	/* USER CODE BEGIN sdmmc1 */
	/* USER CODE END sdmmc1 */
};

Strange since this supposed to be properly generated by CubeMX.

I have both of those sections but I was pasting from my phone and for some reason, it truncated the file.

Hi @cfilipescu​ ,

I understand here you are trying to boot from SDCard. How did you populate the SDCard ?

Did you succeed to do it with CubeProg in serial boot mode ? or did you populate it on PC ?

Also, please confirm you successfully boot exact same hardware with a precedent software version ?

Thanks,

Olivier

Hi @Community member​ ,

Yes, I am booting from SDcard and I populated it using the PC.

https://github.com/bootlin/buildroot-external-st#flashing-and-booting-the-system

dd if=output/images/sdcard.img of=/dev/sdx bs=8M oflag=sync status=progress

Yes, I can boot exact same hardware with a precedent software version that uses "legacy" BSP partitioning without FIP.
