Hi,At my company, we develop debuggers and are trying to access STM32MP257F-EV1(ES) board via the DAP,Unfortunately, we are unable to access the DAP and it seems like JTAG (DAP) access is prohibited by hardware.The result was the same even after shor...
Hi,My LCD display format is RGB666, I removed the "LCD_R0,LCDR1, LCD_G0,LCD_G1,LCD_B0,LCD_B1" in file "stm32mp15-pinctrl.dtsi", and recompile my device tree, then upload to my board. I tried to use the LCD_R0 as GPIO with command: gpioset gpiochip7 2...
Hello,is there any example how to configure LTDC device tree entry for RGB display ?Documentation is unclear on that, only MIPI mode is quite well documented.RegardsArkadiusz
Do the SPI interface need an entry in the SCMI file, as what I2C requires to work ?if yes, So far could not find the exact entry for SPI2. According to the SCMI wiki not, but you never now. (:-))
Kernel tree does not assign any driver to pin PZ2. After gpioset -c gpiochip11 2=1, the pins goes actually high (from low) but the gpioset program stalls. SSH at that moment into the device shows: line 0: "PZ0" input line 1: "PZ1" input line 2: "PZ2"...
