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...
Hello,I am trying to set a static MAC address on an STM32MP157 board via U-boot, I have been following this guide.https://wiki.st.com/stm32mpu/wiki/How_to_update_OTP_with_U-Boot#:~:text=The%20fuse%20command%20allows%20you,(for%20a%20temporary%20updat...
I'm trying to perform the first boot on the STM32MP257F-EV1 following this guide: STM32MP25 Evaluation boards - Starter Package. I've connected the LCD screen to the board according to the instructions.The board is powered by USB-C on CN21, and the ...
