Dear ST team, Hope you're doing well.We have developed a custom board based on STM32MP151 with emmc. Currently, we are using STM32MP151 for flashing. The problem is each flash is taking around 15 minutes time and it will be a critical issue in our p...
error is logged as > Label or path sram not foundThe DTS file at the failing line reads &sram{ dma_pool:dma_pool@0{ reg = <0x50000 0x10000>; pool; }; }; I'm assuming this is to specify where the SRA...
Hi,I have a problem with hanging up my board occasionally when an issue from the console reboot.I read about and the internet says this is a problem with the EMMC memory's power cycle.So I followed by a linkhttps://github.com/orangepi-xunlong/openwrt...
Hello. We already have a custom board based on STM32MP151CAD3 with an eMMC. The following pins are different with default eMMC pins.SDMMC2_CMD: PA0SDMMC2_D1: PB7 As not default pins are used, we need to update OTP value. Here are my result. OTP3 = 0x...
Hi, let us know, for this development kit,1. Linux customization possible.2. support for development
Hello, I built an image with the following configuration by using the ST wiki pages:STM32MP157D-DK1 Evaluation BoardYocto KirkstoneSTM32MP1-Ecosystem-v4.1.0meta-java layer (branch kirkstone)I have used the following command to create an image:./creat...
Hello, In order to use the non-default QSPI boot locations, my understanding is port0-port3, 4 signals need to be defined in OTP words 3, 5, and 6 based on a similar question about SDMMC1 discussed here:https://community.st.com/t5/stm32-mpu-products/...
Hello,We are using the STM32MP151 custom board microprocessor with an external flash memory (emmc). At start-up the board and linux boot correctly, but when reboot it, the board keeps in uart/usb boot loader mode and doesn't boot. It happen also when...
Hello,I've been trying to boot my STM32MP157F-EV1 evaluation board from the SD card but I get the result that is shown in the image when using minicom. I used to work on the board for a long time with no problem, but recently I tried booting it again...
Hello,I try to connect a popular Arduino board PCM5102a with my board which is base on STM32MP135.I read some documentation from the linkhttps://wiki.st.com/stm32mpu/wiki/ALSA_overviewhttps://wiki.st.com/stm32mpu/wiki/Soundcard_configurationhttps://w...
