I'm working with the BF527. My application is similiar to the Blackfin\Examples\ADSP-BF527 EZ-KIT Lite\Drivers\UART\Autobaud example.
Can anyone tell me what the error ADI_UART_EVENT_OVERRUN_ERROR code: 0x40120004 means?
the ADI_UART_EVENT_OVERRUN_ERROR indicates that the OE bit is set, which indicates that a start bit condition has been detected, but that there is already data in the receive buffer (UART_RBR) and the internal receive shift register (RSR).
New data will then overwrite the content of the buffers. You need to ensure that the UART_RBR register is read in time.
that means a receive buffer (RBR) overrun occured. The OE bit in the line status register got set.
Retrieving data ...
