Debugging of Cortex M4 in Stm32MP157

Hello   We are using STM32MP157A-dk1 evaluation board. To this we are writing bare metal code in SEGGER Embedded Studio.   We have written code for all three cores (A7_0,A7_1,M4). Individually we are able to debug(with limitations), For final testing...

I want to use additional UART port in u-boot along with existing UART console. How can I do that, I had made necessary changes in dts file, like enabling the status to OKAY. I am stuck at, How to initialize a particular serial port using u-boot cmd?

I am using STM32MP1 EV board.

USB port 2 cannot be recognized!

We built a customised board based on the stm32mp175c-dk2, with some changes, one of which was the addition of two USB type-c connectors.When I try to use the USB in DFU mode, everything works fine, as long as the boot switch is turned off. When I tur...

A callback() for GPIO in the A7-core on the Linux side of the STM32MP157F

Hello,I'm working with STM32MP1-DK2. I want to run a project on it.I need to implement a callback function in the A7-core (Linux side) to read a pin whenever a signal comes in (on the rising or falling edges).Actually, I need to have a callback() fun...

OPENAMP send data from M4 to A7 and wait until RX buffer is free

Hello,I need to send several kilobytes of data from the M4 to the A7. However, I am experiencing data loss during this transfer. Is there a function that waits on the M4 side, until the A7 has collected all data from the tty./* * Channel direction a...

STM32MP157D using otg as a device with micro-b connector ,and computer cannot find it.

I'm trying to set otg on stm32mp157d in device only mode, according to the guidance on OTG device tree configuration - stm32mpu (stmicroelectronics.cn), &usbotg_hs { compatible = "st,stm32mp15-hsotg", "snps,dwc2"; phys = <&usbphyc_port1 0>; ...

what can be the maximum packet size to be sent over OpenAmp from the M4 to the A7. ,is there any limitation.?? How we can maximize the data throughput over OpenAMP.
