Hi all, I am trying to switch to using FIT images and I am looking at the example .its file here:https://github.com/STMicroelectronics/u-boot/blob/0e6522cbd1bfccd7281acdf8ab5ebbd37d29eab1/board/st/stm32mp1/fit_kernel_dtb.itsI am trying to understand ...
Hi all,The file include/configs/stm32mp1.h in U-boot defines CONFIG_LOADADDR to 0xc2000000. I understand this is the address in RAM where u-boot puts the uImage loaded from persistent storage (SD, NAND, etc).At the same time, according to [2], the ke...
Hello.I created a custom device tree in CubMH and added its instructions "How to create your own machine" (https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine)I wanted to run I2C5 in production mode. Running my code stops CM4 and CA9, wh...
Hey Team, I'm trying to get through a board bring up with the STM32MP157 silicon ver 2001 marked with a Z. We are trying to boot the system from the on board eMMC (Insignis Technology Corp P/N: NSEC53K008-IT 8GB eMMC ) and are having issues. We have ...
Hi,I am currently using the STM32MP1-DK1 board in engineering modeWhen I am debugging the program and stepping instruction by instruction in IAR, the debugging process is lost at a time during the execution.I can execute the program and and I can ins...
I'm trying to get the OpenSTLinux build environment up & running for the 1st time, following the instructions on the wiki step-by-step.So far I have:Built a Ubuntu 18 Virtual machine in Virtualbox - (18.04.5LTS, 4 cores, 8GbRAM, 500Gb HDD)Followed al...
In our custom board we are using I2C1 to control and configure STPMIC1. I'd like to use I2C1 in TF-A so PMIC can be configured to power DDR during boot. I2C1 is not supported by default in TF-A, but looks like there is a way to do it as described in...
I'm trying to boot an STM32MP157 using the v5.4-stm32mp branch of ST's Linux kernel, and it doesn't appear that peripherals under the simple-bus node in the DTS file are getting probed. I copied the stm32mp157d-dk1.dts file as a starting point, but s...
I am on environment 2.0.0 and a custom board with PMIC and STM32MP151 booting via serial interface with the STM32CubeProgrammer using UART4 for debug output.I managed to get the TF-A running up until it is in BL32 (sp_min) and prints "Preparing exit ...
