Looking at the code, i see file sf_probe.c with .id = UCLASS_SPI_FLASH, that performs the id reading. How can i use stm32_spi.c with .id = UCLASS_SPI, driver instead? and send "raw" spi data?

I noticed that after I flash the ST starter package root filesystem, at first boot there is a check on bad blocks and a resize of the partitions, while when I flash the exported root filesystem, there is no checks and some partitions are not resized ...

In this way, error never occurs leading to wrong baudrates. if (pclk != 0U) { /* USARTDIV must be greater than or equal to 0d16 */ usartdiv = (uint16_t)(UART_DIV_SAMPLING16(pclk, huart->Init.BaudRate, huart->Init.ClockPrescaler)); ...

Hello, my main seriale console should be USART2 instead of UART4. I modified the kernel dts as follows: chosen { stdout-path = "serial0:115200n8"; }; aliases { ethernet0 = &ethernet0; mmc0 = &sdmmc1; mmc1 = &sdmmc2; serial0 = &usart2; ...

Hi,This is the device tree configuration i used &spi1 { u-boot,dm-spl; pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi1_pins_a>; pinctrl-1 = <&spi1_sleep_pins_a>; status = "okay"; cs-gpios = <&gpioz 3 0>; };and i also reverted all modific...

Hi @Community member I tried command dm tree and noticed the following:spi 0 [ ] stm32_spi | |-- spi@44004000spi 1 [ + ] stm32_qspi | |-- spi@58003000so I figured out that qspi was actually enabled. I disa...

Hi @Community member I worked some more on this issue and I noticed that inside spi-uclass.c file, the function ret = uclass_get_device_by_seq(UCLASS_SPI, busnum, &bus);put in bus a udevice parent with name spi@58003000 that is the QSPI base address...

Hello, i'd like to use u-boot command sspi to send commands to a spi device with a custom protocol (not a memory). However I see that the command tries to read an ID as it is talking to a flash nor : unrecognized JEDEC id bytes: 00, 00, 00.

Hello, I've exported our custom root filesystem from a running board with the following command: dd if=/dev/mmcblk1p4 of=/usr/local/rtfs.ext4 bs=1M conv=fdatasync

Bug in uart init function when setting baudrate register (BRR). In file /Drivers/STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_uart.c at line 3201, it calculates usartdiv casting it to uint16_t and then checks if it is less than 0xffff.

MicroSD initialization timeout. When inserting the sd card, dmseg shows "mmc0: error -110 whilst initialising SD card" With some logs, i see that mmc_send_app_op_cond is the function that timeouts.

Change default tf-a and u-boot serial linux console.
