Resolved! STM32MP1 OTP word 10 and 11
Hi, I'm trying to leverage the capability of lower words to be programmed once to one bit by bit to implement a sort of "forever growing counter", not sure if there is a proper naming for this.In the lower OTP zone, if I understood correctly, word 10...
Resolved! STM32MP1 DSI voltage level
I would like to clear up some confusion regarding the DSI VIO, the stm32mp157a datasheet mentions "1.2 V I/O for DSI interface" but in the EV1 kit the LCD used (the RK055AHD042-CT, for which it's impossible to find a datasheet for, could that be shar...
On a linux stm32mp157 system can gpio with pullup or pull-down resistors be configured in user space ? If yes how?
I just spent a day trying to configure a gpio with internal pullup using gpiolib. Could not get it configured. Then spent 2 days with device drivers and device trees, and got it working. Seems insane to me that configuring gpios should be this comple...
Cannot load STPMIC1 regulate driver
I have a customized STM32MP157AAD board with STPMIC1E PMIC.STPMIC1E is pre-programmed to have same NVM as 1A version.After power up, the board can download firmware by CubeMX and run uboot from SD card, even partially boot the linux kernel.However, t...
