NUCLEO-U575ZI-Q / Ux_Device_CDC_ACM example: USB->USART transmission issue #5

Closed djix123 closed 2 years ago

djix123 commented 2 years ago

OS: OSX 12.1 IDE: STM32CubeIDE: 1.8.0 (fresh installation, all defaults)

Application builds with no errors, but when data transmission from USB->USART does not work correctly. Only 1 character is transmitted, second and subsequent characters do not appear. By contrast, USART->USB works correctly - all characters are transmitted.

It appears that the call back HAL_UART_TxCpltCallback is not called on second and subsequent characters.

[Both the USB and USART via STLink VCP are connected to using screen]
