Hi all,
I have a CORTEX (STM32F103VEH6) processor and a NIOS II processor....
I am trying to communicate between these processors using UART communication...
I send fixed Data from NIOS to CORTEX at regualr intervals....
AT CORTEX for reception of data i have configured a DMA....
The problem is after some time The CORTEX processor stops receiving data from NIOS...though i have checcked that NIOS processor keeps on sending the data....
I checked the CORTEX processor through debugger, the uart Data register doesnt update neither does the RRDY bit sets which indicates that a data is received...
more to add, there are no overrun or any error on CORTEX UART or DMA peripheral...
I am communication at 2.25 Mbaud RATE...
Don know why CORTEX UART is not receiving data though the NIOS is sending data...
PLEASE HELP>>>>>THANKS A LOT IN ADVANCE
