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...
After removing ”weston-start“ app, other apps cannot be displayed on the STM32MP257 platform
Hi:Recently, while developing an application on the STM32MP257, I tried to remove Weston. After removing the weston-start application, other apps could no longer be displayed. Additionally, when using modetest to check, I noticed that the CRTC sectio...
Resolved! HAL_SPI_Transmit_DMA() succeeds once; subsequent calls return HAL_BUSY
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...
Resolved! STM32MP157AAD3 Heat dissipation
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...
Resolved! STM32MP13x PDR_ON floating - random boot issue?
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...

STM32MP157 unable to boot from SD
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 ...
Resolved! uint8_t Values Are Not Changing
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...
