Hello to everyone!We have develop a System on Module board based on the STM32MP153AAB. Currently it have a custom Yocto Image build, that it's working. The process followed almost all the steps in the wiki for the STM32MP157F-DK2 discovery kit, howe...
I want to test the memory by using U-boot.I'm reading the DDR memory from 0xC0000000 to 0xE0000000 with the pattern 0xFFFFFFF. But I don't have premision to read the memory. How can I solve this issue? STM32MP> mtest 0xC0000000 0xE0000000 0xFFFFFFFF...
Dear All,I have been developing touch screen with XPT4096.When press touch screen, interrupt is generated.Read Y, X, Z1, Z2, power down is sent to XPT4096.During transferring message to XPT4096, transfer setup failed.Please refer to waveform.1CH : sp...
I can fix the problem by enabling interrupts for the DMA channel. But WHY should this be necessary?I'd prefer to do this with no interrupts. I allow ample time between calls so data transfers have plenty of time to complete.(G4 chip, MX set up as SPI...
Why does the STM32MP157AAD3 have a higher heat or temperature? We have an STM32 board that has interfaces for PMIC, DDR3, temperature sensors, VOC, EMMC, LEDs, push buttons, WIFI+BLE modules, 8-pin connectors, wake-up switches are build in same board...
Hi, we have a custom design with an STM32MP13xx CPU.We currently see random issues during boot. Some of the prototypes randomly stuck on boot without any output on the serial console, sometimes they are booting well. When a board has booted it runs s...
Hi,I am trying to migrate my project (custom board using stm32mp153a and 256MB mem) from 4.1.0 to 5.0.0 but I am getting a panic when booting u-boot:Board: MBfdd8 Var2.15 Rev.B-14 DRAM: 256 MiB E/TC:0 tzc_it_handler:79 TZC permission failure E/TC:...
As part of our project, we are using an STM32MP157DAC custom board that has the same design with the STM32MP157D-DK1 development board except for a few changes (schematics of the design is attached)The board generally works when trying to upload and ...
I want to download and use firmware (FW) to DDR3. Since DDR is initially disabled, the firmware to activate DDR and the main FW project are separate, and the download procedure is as follows:First, run the DDR activation FW to enable DDR.Download th...
When I use sp_ min, I use the following command to generate fip in the Bareenvironment, and can start the u-boot normally:fiptool create --tos-fw bl32.bin --nt-fw u-boot-nodtb.bin --fw-config stm32mp157d-***-fw-config.dtb --hw-config stm32mp157d-xx.d...
