Booting OS in PCIE SSD adapter
Hi,We are wondering that do we support to boot uboot from nand flash then boot into OS from external PCIE SSD driver.Is that workable to support this case by changing codes on stm32mp257 platform? Thanks.

How to set up Gigabit Ethernet in LWIP under STM32MP135 bare metal RTOS
Hello: I am debugging the network development of STM32MP135 bare metal, using the protocol stack LWIP+FreeRTOS, and I have implemented the LWIP transplantation of dual network ports under FreeRTOS, and can successfully PING the IP of the two network...
MP1 SWD access probably tristates all GPIO sometimes
I'm testing STM32MP157A for our new projects. The MPU VCC is 1V8, USB is 3V3. Debugger is connected to two SWD pins. One of first test is:boot into DFU loader, upload simple code to 0x2ffc2500:S_GPIO_ALT(GPIOA,13,2); S_GPIO_ALT(GPIOA,14,2); RCC->MCO1...
Unable to read the internal ADC in STM32MP157A
We are using STM32MP!57A processor in our custom board. In this we are unable to read the internal ADC values in our cards. Actually, we initialize the internal ADC pins in cortex-M4 core with support of STM32CUBEMX and debug in CubeIDE...
Timeout error occured while waiting for acknowledgement
i am trying flash in SD card for STM32MP157F-DK2. I am getting the error as mentioned below Port configuration: parity = even, baudrate = 115200, data-bit = 8, stop-bit = 1.0, flow-control = off16:56:09 : Activating device: OK16:56:09 : Board : --16:...
Resolved! STM32MP157 Change LTDC_CLK frequency after wakeup from deep suspend
Hello everybody,I am developing a custom board strongly inspired by the STM32MP157D-DK1, except that I use a parallel DPI RGB on 24bit display.I use openstlinux-6.1-yocto-mickledore-mpu-v24.06.26.The frequency of "LTDC_CLK" changes by itself after wa...
Is there a way to use the B-LCDAD-HDMI adapter (bridge chip ADV7533) instead of the default panel DSI on the STM32MP157a-ev1 board?
Hi,I tried to update the DTS to make use of the adapter but unfortunately without success. These are the change I made:hdmi-out { compatible = "hdmi-connector"; type = "a"; port { hdmi_con: endpoint { remote-end...
FWU on stm32mp25
Hello,I have a STM32MP2 platform with A/B partitioning for TF-A, metadata and FIP.I'm looking for a way to generate a test FIP and install it in FIP-B bank, have TF-A load it, if this FIP contains a bad signature or other error that will prevent Uboo...
STM32MP131 One Pulse Mode with PWM
Hello,I am trying to generate output with adjustable pulse width using One Pulse mode.The output pin is in a Pull-Up state, with an initial state of High. When One Pulse mode is activated, it outputs a Low signal for the specified duration.However, t...
Resolved! Should I use length matching on all differential pairs?
Even if I route the differential pairs, one pair will always be longer than the other.Should I route an extra path, like a sawtooth or tromebone on the shortest pair to make booth differential pair equal in length?I see that the STM32MP1 dev-kit does...
