I have only one MMC, in this case it's an eMMC on SDMMC2. I have some issues when I loading over the TF-A and the FIP.bin file.Update:I have change the clock frequency to 49.5 MHz and measured the v3v3 signal to 3.3V and the vdd signal to 3.3V as wel...
Hello We have built OpenSTLinux(Openstlinux-6.1-yocto-mickledore-mp1-v23.06.21) for stm32mp157f-dk2 Board and I have built st-image-weston image. Iam new to this Yocto,so I request you to help with the following:How to make changes in dts & dtsi file...
I never heard about the PER clock. I'm looking inside CubeMX, but I don't see any PER clock at all. I guess it's periferial clock. So how do I start it? My U-boot won't boot. I guess that if PER will be like 24 MHz, then U-boot will continue. Or am I...
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...
stm32mp157f, I need to use uart5 to drive an rs485 but the hardware supplied DE pin is already in use. So I need to configure a different GPIO to use. If the device tree binding rts-gpios is supported, then the task is simplified. We can modify the...
I'm facing the issue were the USB connection is re-connecting, which results that STM32CubeProgrammer re-flashing the device over and over again when the fip-boot has be fully loaded. So what can cause this restarting and re-connection? Is it somethi...
Hi,We are using STM32MP157CAA3T processor. We have implemented USB, UART and SD card for Booting purpose.And currently we are programming the processor via UART8 by using USB to UART convertor.Used UART4 Debug port for troubleshooting the board.Probl...
I think this one might be very easy. It's just a configuration I need to set, but I don't know what configuration I need to write.We can begin with the error log. The error is about the clock for the MPU. It as not been set yet and I don't know why. ...
I have seen an example diagram of STM32MP13X + RTL8363NB in the AN5474 document, how can RCC be implemented in software to provide 125MHz and where can I find the code for that example?
It's fun to debugging the output when I flashing the processor/eMMC from CubeProgrammer via USB. But it's less fun to not knowing the cause of the error.What can it be in this case?Do I have forgot the sett the board ID, is the unknown VDD the error?...
