Linux running on A7 corrupted when FreeRTOS with virtual uart application running on CM4 freeze. How to fix this in Linux 5.4.31?

2021-02-04
We have an virtual uart FreeRTOS application running on CM4, it captures SPI data and sends to A7 through virtual uart. Sometimes, the FreeRTOS application freezed, A7 can not read the data through /dev/ttyRPMSG0 again, at the same thime, Linux 5.4....

MIPI DSI display flicking at 1280x720@60

2019-09-25
 Dear team,We have a design with stm32mp157aac MPU, and we use MIPI DSI as the display interface to a device with 1280x720@60 RGB888, the PCLK is 74.25MHz, the DSI works at non-burst sync event video mode. But the image is flickering continously. Whe...

We have a design with a USB HOST, the schematic is shown below， And the system is Linux 4.19. We have add some configuration about USB HID as below: 2 CONFIG_HID=y 3 CONFIG_HID_GENERIC=y 4 CONFIG_USB_HID=y 5 CONFIG_USB_HIDDEV=y 6 CONFIG_USB_KBD=y 7 ...

Whether the size of FSBL is limited to one block of NAND, and shell we tailor the FSBL(tf-a) within 128KB to fit MT29F4G08，which block size is 128KB?

2019-08-21
Hello, we are using a NAND Flash MT29F4G08 as boot device, which block size is 128KB. We program the 245KB size of FSBL(tf-a.stm32) to it with cubeProgrammer successfully, it does not boot up. When we replace the NAND Flash with MT29F8G08 as boot dev...
