We have a custom board based on STM32MP157 MPU and running AOSP, with AUO G101EVN010 LCD-TFT panel using an LVDS to LTDC converter for interface.Setup of the system is done using the STM32MP1 distribution for Android. I am able to get the panel to di...
Using the STM32MP157 development kit, I have configured two "GPIO Analog" lines that are exposed through CN13 (pins 1 and 2).I am trying to set these up as such. From going down the rabbit trail of documentation:https://wiki.st.com/stm32mpu/wiki/GPI...
We are using ST32MP153 running mainline linux on the A7 cores. And we want to use the M4 for realtime processing and output. Therefore some resources shall be used by Linux at the A7 cores. Some by the M4. If we get it right, ST's solution for that i...
Hi Team,We are trying to boot the STM32MP157A-EV1 board with our eMMC device, but it is booting intermittently.As per our debugging the failure case, eMMC device will respond ACK within ~15ms but ROM code disable the CLK in ~50ms(before downloading t...
