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...
Hello,I am using an STM32WB05KZ on a custom PCB. Initially, I was able to program it normally via SWD using STM32CubeProgrammer, but after uploading a BLE Beacon example, I can no longer connect to the MCU.CubeProgrammer now shows:Error: Unable to ge...
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...
