STM32 MPUs Products and hardware related

Resolved! I just received STM32MP157F-EV1. On boot, the LCD displays nothing and the onboard ST-Link will not properly enumerate (Windows says "USB Device Not Recognized"). Latest ST-Link driver is installed and working with other kits. Is this a faulty board?

The ST-Link LEDs are very dimly lit when powered...they are much brighter on my STM32MP157F-DK2 board. I suspect some hardware problem with the MPU board. Also, the CPU LEDs do appear to be running (the Linux Blue LED blinks after a while, and with...

How to change the sample rate for the simple-audio-card on STM32MP151A. Right now it seems to be set to 48KHz. I don't have access to the devicetree, therefore, I would like to modify the driver. The sound-card is using I2S format and SAI2 interface

Bluetooth tty instance not showing up in /dev/tty*

Hi,I'm using a Wifi/BT module with CYW4343W chip on a custom board with STM32MP157.When booting the system, the driver is loaded correctly and dmesg log shows[ 1.089865] 4000e000.serial: ttySTM1 at MMIO 0x4000e000 (irq = 24, base_baud = 6250000) i...

Use lan9303 in mdio mode on STM32MP157

Hi,I am trying to use the lan9303 chip in mdio managed mode on a stm32mp157-based board.I configured the Device tree according to https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next/+/refs/heads/akpm-base/Documentation/devicetr...

Resolved! Device tree and clock configurations

Hi,We are using the STM32MP157f-ev1 board for our initial development and this is our first time using Linux kernel, we have been following the development package wiki links for building kernel, u-boot and tf-a. We used the STM32CubeIDE's inbuilt cu...

Resolved! On dk2, how can I get the ST-Link microUSB port connection to enumerate?

As stated in the title, I'm having trouble getting the ST-Link microUSB port connections to enumerate on the PC (Linux). I have two of the dk2 boards, and they have the same behavior. The only way they enumerate on the host is through the DFU mechani...

Resolved! How to configure 512MB*2 DDR ram in u boot?
