stm32mp157a-dk1 : Error u-boot with basic boot mode "stm32mp1_clk_get_id: clk id 69 not found"

kghal.1 · ‎2022-08-23

I built u-boot for stm32mp157a-dk1 board with basic boot mode:

Defconfig: stm32mp15_basic_defconfig

Device Tree: stm32mp157a-dk1

I got this error at starting u-boot and if I try to read/write from/to OTP register:

Hi,

For information, in include/dt-bindings/clock/stm32mp1-clks.h

#define BSEC 69

this BSEC clock is added in kernel device tree, provided by SCMI for trusted boot, and need to be supported in U-Boot clock driver for basic boot (even if no more supported in OpenSTlinux)

drivers/clk/stm32/clk-stm32mp1.c

STM32MP1_CLK_SET_CLR(RCC_MP_APB5ENSETR, 16, BSEC, _UNKNOWN_SEL),

I think this patch is missing in your U-Boot (OpenSTLinux v3.1 ?):

clk: stm32mp1: add support of BSEC clock · STMicroelectronics/u-boot@28e5ace (github.com)

Regards

Patrick

Hi kghal.1 (Community Member),

On the latest OSTL DV4.0, only Trusted boot with FIP OPTEE or SP_MIN is supported. Basic boot is no longer.. https://wiki.st.com/stm32mpu/wiki/STM32_MPU_OpenSTLinux_release_note_-_v4.0.0

Hi kghal.1 (Community Member)

Are you now sorted out taking the trusted package?
