Still trying to get a custom board with a STM32MP151AAC and 512MB ram to boot from eMMC. Switched to using this guide.After various new issues (one of them being this), I managed to bitbake a set that I'm able to fully program with CubeProgrammer.How...
On STM32MP1 discrete power. 512MB DDR , TF-A & OPTEE configure in SYSRAME/TC:0 0 Panic at core/arch/arm/plat-stm32mp1/cpu_opp.c:106 <set_clock_then_voltage>Log attached.This message seems to unique for stm32mp1 in OP-TEE code. no other platform sou...
Hi All,I have an question when i used STM32MP157.I encountered an issue when using DMA to store the values of ADC conversions.When I store the data from the ADC_DMA_Buffer to the ADC_DATA_Buffer in the HAL_ADC_ConvCpltCallback() function.Then check t...
Hey all, I'm trying to test DRM/KMS on an STM32MP1 board, but I can't do this while weston is taking over DRM. The documentation says to quit weston, then run any KMS stuff while it's not running. This is all well and good, and this is the way it's s...
Hi ~I am using STM32MP157C MPU + STPMIC1A for my custom board with ecosystem 4.1And unfortunately I'm wrestling with some problem regarding PMIC.I produced 30 boards for sample.Some board is working fine but some board has power issue.1) Custom board...
When we use the PMIC values from DK2 example.1 . ERROR: regul ldo3: max value 750 is invalidWARNING: register_pmic:600 failed to register ldo3PANIC at PC : 0x2fff05cb2 Next we tried setting the ldo3 max, min values to 3V and 1.8V and it was working ...

As in a different post, The TF-A build did not create the FIP binaries after deleting the FIP build folder.This article does not describe how to create a new FIP binary. only how to update. very confusing !The fiptool does provide a create function b...
Hello,The QC for STLINK-V3PWR assembled in France seems to be very bad. I received a unit that doesn't work out of the box (when USB is connected the status leds stay off, AUX power outputs 3.3V, host computer doesn't detect V3PWR).The same host comp...
Hi, I have an STM32MP135F-DK board, and I want to set LDO2 and get an output voltage of 3.3V. I have read a document ( Integration of STM32MP13x MPU product lines and STPMIC1D / STPMIC1A on a wall adapter supply) which states that LDO2 must be set af...
