I have built an main application (using HAL) and a bootloader project (using LL).When debugging seperately, the UART reception using interrupts works well in both projects.But after I jump to bootloader from main application, immediately after re-ini...

A simple compare between the two HAL Versions shows that line 4730 "huart->ReceptionType = HAL_UART_RECEPTION_STANDARD" needs to be moved at position line 4708. This fixes the bug, same as it is implemented in HAL For STM32F0 series

Sollution found after a while...Turns out HAL_UART_MspDeInit(&huart1); only turns off the clock to register, but does not reset register.. Main app enabled various uart interrupts (idle, parity error etc.). So when the bootloader activated the clock,...

Problem with UART Interrupts (ICSR->ISRPENDING always 1) after jumping to booloader from main application

BUG found on HAL STM32L4 HAL_UARTEx_ReceiveToIdle_IT(). This function works on STM32F0 HAL V1.11.3 but not on STM32L4 V1.17 An update is needed to solve bug when UART bytes is equaly to RxXferSize, because currently it stays on endless IT loop
