We plan to design a stm32mp13x board equipped with 8MB psram using FMC interface as system RAM. It's going to be very slow but that's fine for our application, and standby power consumption is the topmost priority in this project. How should we deal ...
Please show me a working example of setting up the MMU for STM32MP157D-EV1. and where to place the Translation table correctly (for cortex A7)It is assumed that all data and program will be located in DDR memory, without using the OS
Hello, I'm trying to boot my EVAL board with the images from STM32MP1 Starter package version 5.0.0.I created a "raw" image from flashlayout_st-image-weston/optee/FlashLayout_sdcard_stm32mp157c-ev1-optee.tsv and flashed it to microSD card using "dd"....
Hi,I have created a device tree for Marvell 88E6185 (10 port switch).Port9 of the 88E6185 is in PHY mode (MII) connected to STM32MP135F Ethernet2. MDIO lines of the Switch directl connected to Ethernet2 MDIO lines.Port0 is connected to Marvell 88E111...
Hello, Can you tell me the differences between two files linker script STM32... FLASH.id and STM32...RAM.id Regards,
This is a request for clarification of the TUR (Time Unit Ratio) calculation in the TTCAN implementation of the FD-CAN peripheral that is part of STM32MP1xxx systems. Specifically: the TUR is composed of a numerator and a denominator, designated FDCA...
Hello, Recently, a STM32CubeMP13 Package has beed added by ST ( here on the wiki, here on github). I tried to use external loader with STM32MP135F-DK board, the same board used in the wiki. First, I used SD external loader, with UART and USB connecti...
We are working on a custom board (based on STM32MP135F-DK) which uses STM32MP131AAE and STPMIC1DPQR PMIC.We are using STM32CubeProgrammer TSV Flashing service to flash the image into eMMC, in this process we are getting a PMIC Panic NOTICE: CPU: STM...
Hello,We have designed our FMC interface using NOR Mode B multiplexed AD-Bus.Checking the actual Revision 6https://www.st.com/resource/en/reference_manual/DM00366355.pdfreference manual this is not allowed, see Ch. 25.8.4 (Pg1365):If the extended mod...
Getting panic error during optee binary update. We are stuck on this. Kindly provide any guidance. We are using emmc for boot and Two file updating till now. But after fip-stm32mp135f-dk-optee.bin update we are getting this error. Here is the log- NO...
