On an existing, working project developed with stm32cubeide 1.19.0 and the stm32h743zit developed with azrtosh7 3.3.0 that uses usbhs as the host for msc and midi devices, I need to add usbfs channel management to connect hid and midi, but I'm having...
Hi everyone,I’m debugging an SMBus issue between an STM32H7, an LTC4100 Smart Charger, and an RRC2054 Smart Battery. I’m trying to write to the ChargingVoltage() register (command 0x15), but the SMBus frames captured on the logic analyzer appear corr...
Hello, I’m working with an STM32H723 MCU and have a question about Flash behavior when caches are enabled.Both D-Cache and I-Cache are enabled, and I’m not using any additional MPU configuration. I'm using D-Cache invalidate after a Flash erase opera...
When I call function HAL_FLASH_Program twice with the same Flash address, the second call is ignored. See test code below.int8_t buffer1[16] = {0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF};int8_t buffer2[16] = {0xF...
