Why not start touch with cubeprogrammer but only with stm32ide

[hjh]

Hi

I do have a program with touchgfx running on a stm32f746-disco.

When program with stm32cibe IDE it starts up and running very fine

BUT when i take the .elf file and program the board with the stm32cube programmer it do not start up touch ..

what do you guys think the problem can be ?

Best regards

Maybe same issue as on other thread











In STM32ToucController.cpp in the generated code I found this:
static void I2Cx_Error(I2C_HandleTypeDef* i2c_handler, uint8_t Addr) { /* De-initialize the I2C communication bus */ HAL_I2C_DeInit(i2c_handler); /* Re-Initialize the I2C communication bus */ //I2Cx_Init(i2c_handler); }
Which I changed to:
static void I2Cx_Error(I2C_HandleTypeDef* i2c_handler, uint8_t Addr) { /* De-initialize the I2C communication bus */ HAL_I2C_DeInit(i2c_handler); /* Re-Initialize the I2C communication bus */ //I2Cx_Init(i2c_handler); HAL_I2C_Init(i2c_handler); }
And now the app works perfectly after a reboot.
I guess the touch controller is maybe starting up slower than the app can handle without the error handling.
