I am trying to build a custom board for the stm32mp151A using the STM32MP15 Evaluation boards as a reference.U-BOOT starts, but the kernel won't start, and I'm at my wit's end.1. When the device starts up, the console displays "CPU: STM32MP151AAC Rev...

Custom STM32MP151A board with 512MB DDR2.I am trying to write via UART communication with STM32CubeProgrammer, but BL32 processing does not start.What should I do to investigate the cause? [2024-01-12 14:11:52.591] NOTICE: CPU: STM32MP151AAC Rev.Z[20...

Please tell me how to set the wake-up button (PA0:PWR_WKUP) as a return factor from LPLV-Stop mode and set STM32MP157f-EV1 to LPLV-Stop mode.

Isn't there a script file for generating RAW images for eMMC like the "create_sdcard_from_flashlayout.sh" file for generating RAW images for SD?Also, why is SD memory mapping different from eMMC memory mapping?

I added optee_framebuffer@dd000000 to the U-BOOT device tree.I hope this helps.reserved-memory {#address-cells = <1>;#size-cells = <1>;ranges;/* USER CODE BEGIN reserved-memory */optee_framebuffer@dd000000 {reg = <0xdd000000 0x01000000>;no-map;};opte...

"vtt_ddr" in the TFA device tree has been left as is, but "vtt_ddr" in the OPTEE device tree has been deleted.　/*　* vtt_ddr:ldo3{　* regulator-name = "vtt_ddr";　*/

The problem was solved by deleting "vtt_ddr" from the PMIC setting in the OPTEE device tree.ThanksKiichi

hi @PatrikFOur custom board is STM32MP151A board with 512MB DDR2.I thought that I should change the STM32MP_DDR_MAX_SIZE below to 512MB. /* DDR configuration */ #define STM32MP_DDR_BASE U(0xC0000000) #define STM32MP_DDR_MAX_SIZE U(0x40000000...

hi @PatrikFI am checking the transition from BL32 (SP_min) to BL33 (U-Boot). BL32 (SP_min) -> BL33 (U-Boot)I confirmed that the sp_min_main() function finishes.I also confirmed that 0xc0500000 was written in the smc_ctx_t table.(0xc0500000 was writt...
