Hi all, Working on STM32H745: when enabling the M4 at M7 main(), the 'D2 domain' SRAMs (1,2,3) are being reset, causing issue, as the M7 and the OS are using these SRAMs, prior of the M4 enable (RCC register). Is there any option not to reset the ...

TDK, thank you for the info, I've managed to set it manually as in the following flow:call HAL_ADCEx_Calibration_Start() //Performs self-calibration wait 10 mseccall HAL_ADCEx_LinearCalibration_GetValue(): get calibrated values (160-bits LINEAR_CALIB...

Thanks for your prompt reply.Right, this works fine, but I want to avoid changing the calibration every power up, meaning i want to have a one-time calibration per product life, as we do a manual calibration in addition to the ADC-self calibration. S...

As i understood, HAL_ADCEx_Calibration_Start() should be called every "startup". Is there a way to call it self-calibration of the ADC once, save the calibration values (e.g. to internal eeprom) and every statup to recall the same self-calibration va...

Hi EBrun, I wonder how did you fix the issue wit the CID= 0x2300, as the first condition in if(((USBx->CID & (0x1U << 8)) == 0U) && (hpcd->Init.battery_charging_enable == 1U)), is not fullfilled, and the USB Transceiver is not enabled.Thaks,Rolf

is it possible not to reset the SRAM (D2 Domain) when M4 is enabled?
