SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32


Touch support after screen rotation F429

Tunisia

I have developped a small code testing this : not clean but works for me ;)

intialization
BSP_TS_Init(320, 240); // instead of 240, 320

stm32f429i_discovery_ts.c
/**
  * @brief  Returns status and positions of the touch screen.
  * @param  TsState: Pointer to touch screen current state structure
  */
void BSP_TS_GetState(TS_StateTypeDef* TsState)
{
  static uint32_t _x = 0, _y = 0;
  uint16_t xDiff, yDiff , x , y, xr, yr;
  
  TsState->TouchDetected = TsDrv->DetectTouch(TS_I2C_ADDRESS);
  
  if(TsState->TouchDetected)
  {
    TsDrv->GetXY(TS_I2C_ADDRESS, &y, &x);//instead of &x, &y
    
    // ......
}
