Hi, I have noticed an issue in a bare-metal application when polling the register XUARTPS_ISR (Channel Interrupt Status Register). No issues when I use XUART_SR (Channel Status Register) instead. The issue: When I poll XUART_ISR for TX_FULL and RX_EMPTY the UART interface becomes an unstable state. No sending and receiving after a few bytes is possible. Has somebody noticed the same issue or can somebody explain whats happening? Edit: My current code for the UART interface (Here I use XUARTPS_SR instead. But when I poll XUARTPS_ISR

Greetings all, I am new to zedboard. This might be a basic question. I want to send some data via UART0 to DDR memory through direct memory access AXI. (GPS data) Again I want to collect another set of data from UART1 and writing it to DDR memory.(GSM/LTE module) Now if interrupt from one UART( UART1) occurs, I want the processed data of UART0 which is on the DDR memory to be read via UART1(GSM module) and send to a remote server. Any suggestions and advice on how can i design the hardware?
