F28M35H52C: UART: 17 characters limit in NonBlocking mode

Part Number:F28M35H52C

Hello,

I'm trying to get the controlSUITE uart_echo example to work, but I can't transmit (from the uC to the PC) more than 17 characters in nonBlocking mode, using the function UARTCharPutNonBlocking(...). I tried with UARTCharPut(...) and it works fine except it slows down the whole system and is not acceptable for me. The goal is to do some logging.

A few other people have mentioned this problem, but I don't think it was directly answered. I've read that this could come from the FIFO being full... ? And/or ISR not serviced quickly enough... what ISR ?

Could anyone explain to me what I can do to transmit longer strings in NonBlocking mode ?

Thanks a lot.
