Need to patch embeddedsw/lib/sw_apps/zynq_fsbl/src/main.c (OutputStatus function)

[kayws426]

• Situation:
  • adds uartps to hw design (but uartps is not a debug channel for the developer)
  • select another uart(ns16550) for STDIN and STDOUT in BSP(for fsbl) setting.
  • uartps should not make any output data on boot
• Problem:
  • fsbl hang on OutputStatus function (invalid baseaddress for uartps)
• Solution:
  • apply patch to main.c

 void OutputStatus(u32 State)
 {
 #ifdef STDOUT_BASEADDRESS
-#ifdef XPAR_XUARTPS_0_BASEADDR
+#if defined(XPAR_XUARTPS_0_BASEADDR) && (STDOUT_BASEADDRESS == XPAR_XUARTPS_0_BASEADDR)
    u32 UartReg = 0;
 #endif

    fsbl_printf(DEBUG_GENERAL,"FSBL Status = 0x%.4lx\r\n", State);
    /*
     * The TX buffer needs to be flushed out
     * If this is not done some of the prints will not appear on the
     * serial output
     */
-#ifdef XPAR_XUARTPS_0_BASEADDR
-   UartReg = Xil_In32(STDOUT_BASEADDRESS + XUARTPS_SR_OFFSET);
+#if defined(XPAR_XUARTPS_0_BASEADDR) && (STDOUT_BASEADDRESS == XPAR_XUARTPS_0_BASEADDR)
+   UartReg = Xil_In32(XPAR_XUARTPS_0_BASEADDR + XUARTPS_SR_OFFSET);
    while ((UartReg & XUARTPS_SR_TXEMPTY) != XUARTPS_SR_TXEMPTY) {
-       UartReg = Xil_In32(STDOUT_BASEADDRESS + XUARTPS_SR_OFFSET);
+       UartReg = Xil_In32(XPAR_XUARTPS_0_BASEADDR + XUARTPS_SR_OFFSET);
    }
 #endif
 #endif
 }

thank you.
