i am having an issue using STM32G4 with I2C DMS and FreeRTOS. I have used the library https://github.com/firebull/STM32-LCD-HD44780-I2C for a long time with STM32F4 and free RTOS and it works perfectly. Now I wanted to use it with STM32G4 but the Problem is: 1. The SCL line stays low when calling: `HAL_I2C_Master_Transmit_DMA(lcdParams.hi2c, lcdParams.address, (uint8_t*)lcdCommandBuffer, 3)` and it only sends the first byte instead of 3 2. The program get stuck in: `while (HAL_I2C_GetState(lcdParams.hi2c) != HAL_I2C_STATE_READY) { vTaskDelay(1); }` The hardware doesn’t have any problem because I can print text without DMA using blocking mode with another driver. I have used USB Scope to inspect the problem and tried a lot of things like resetting I2C with https://electronics.stackexchange.com/questions/267972/i2c-busy-flag-strange-behaviour or reducing the speed but nothing worked. I have used the same configurations that worked on STM32F4 with STM32G4 in CubeMX but HAL_I2C_Master_Transmit_DMA is not sending the other bytes and the bus is held Can someone help me please? Thanks. update 1: I changed the 3 functions to transmit in the library from DMA to blocking mode but not with DMA.
