Hi, Everybody! Could anyone help with correct device tree for qspi-nand flash. I can't see any activity on pins connected to flash. If I try to boot from spi-nand with BOOT0..2 set to 1, I can see clear SPI transactions... So, flash connection looks ...
I'm connecting a X-NUCLEO-PLC01A1 with my DK2 card. The Inputs are working fine and for the outputs I can read the fault status , I'm getting 0000 0000 1000 0101, then all is right, the 3 error leds are off, and the OE signal is in 0 (I tested also w...
We are having issues with STM32MP157 UART7 (address 40018000) exiting low power CStop mode and waking up Linux (v4.19 from ST github).We have confirmed that CStop mode is entered, and it can be exited using an external interrupt (55 pmic_irq), howeve...
I would like to understand why I cannot find and enable STM32 SPI support in the Linux kernel and resolve conflicting information in the Wiki articles I am using.When I use menuconfig, I cannot locate STM32 SPI support in the menu. If I use the searc...
I was trying to test the ADC of a STM32MP157C-DK2. I downloaded a basic example program to perform the data acquisition in the M4 processor (https://github.com/STMicroelectronics/STM32CubeMP1/tree/master/Projects/STM32MP157C-DK2/Examples/ADC/ADC_Sing...
I apologize in advance as the question is really a basic and obvious one ... My custom board is using an STM32MP151 SoC.Is it possible to re-write programmed OTP bits (namely, OTP Word 3 for boot modes).My feeling is that, this is not possible (One T...
Hello,I am using an stm32mp157c-dk2 and browsed the stm32mp1 workshop MOOC : https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/STM32MP1_workshop.htmlI tried launching the pre-configured VM given here : https://drive.go...
Hello everyone,I'm currently working with a STM32MP157c. This microcontroller includes multiple timer peripherals (General-purpose timers / Advanced-control timers) and also ADC peripherals. Therefore it is possible to trigger the ADC conversion by a...
I want to know how to use ta to get the startup log information during the bl32 startup phase or if there is another way to store the log information so that I can get it in the bl32 phase
