Hello, we are using a NAND Flash MT29F4G08 as boot device, which block size is 128KB. We program the 245KB size of FSBL(tf-a.stm32) to it with cubeProgrammer successfully, it does not boot up. When we replace the NAND Flash with MT29F8G08 as boot dev...
I've been trying to reduce power consumption of the STM32MP157C-DK2 board and have a very low power linux platform. But the power consumption seems somewhat agnostic of power rails and clock rates. For example, I removed the LCD, I boot to u-boot, th...
I added nand flash to stm32mp157aac, but the nand startup mode is always DFU mode, may I ask what configuration is needed?Nand boot has been selected on the hardware
Hi. I am using the Uart Bootloader from the ROM.I want to write my Programm to the Sysram at 0x2FFC3000. I don't know why, but the Software ignores my commands.It accepts the write Command, it accepts the adress. But when i write the Address it twic...
I've spent some time looking over the STM32MP15x hardware manual but cannot confirm that the FMC levels (in SRAM mode) are 1.8v. Can this be confirmed or corrected please?
I'm trying to develop an application that puts the A7 into a low power mode and only uses the M4 to do some basic processing. I'm starting with the OpenAMP_TTY_echo_wakeup example. In the example it says to issue the following commands:echo "*delay" ...

Just wondering if I can edit the pinctrl.dsi file to change the pins to the Raspberry Pi header, rather than the HDMI encoder, so I can try DPI Raspberry Pi displays. In CubeMX the LTDC and most of the peripherals are locked, just wondering if it is ...
