Hello,We are using stm32mp157A processer in my custom board.We need to change voltage values in Arm trusted firmware (TFA 2.5) dtsi file .For that we changed voltages as per our custom board but it is not effected.vdd: buck3 { regulator-name = "vd...
Hey I found a strange documentation on your wiki pagehttps://wiki.st.com/stm32mpu/wiki/STM32MP15_OTP_mapping 3: 14-7 (8 bits)UART instances disablingIf it is different from zero, then each bit disables an UART instance.Collapse0b00000001: reserved0b0...
I guess there is a typo on the following page (and i couldn't find the proper place to report that)wiki.st.com/stm32mpu/wiki/SPI_device_tree_configuration"Both /delete-property/dma-names and /delete-property/dma have to be inserted to get rid of DMAs...
What does the OTP 9 Bit 0 do?There is nothing in the ref manual.
What does the OTP 3 Bit 15 do?Can I disable the boot cache for more security? Or does it have more impact on the system?
The flashing process of our STM32MP1 SoM is very slow, it took about 3 and 1/2 hours to flash to whole 8GB eMMC. We use the STM32_Programmer_CLI and have a usb connection which shows up in DFU mode. How can we speed up the flashing process? How coul...
I've written a script that basically builds everything based on this wiki - wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#Updating_the_kernel_device_treeWith the script I can successfully build from the existing ...
Hi,how to compile fsbl to test ddr3 purposes. Unfortunately, I can't use the official one due to different UART4 debug pins and I2C4 PMIC. I can't find a good link with simple instructions. Maybe someone gives me a link or short instructions on how t...
I have to read ADC readings from 4 channels on both ADC1 and ADC2. In production mode, when OPENAMP isn't enabled, everything works as expected; however, when it's enabled, two channels are getting garbage readings. I do not know why or how to fix it...
