problem

The debugging error of XILINX ZYNQ SDK is as follows:

Memory read error at 0xF8007080. AHB AP transaction error, DAP status f0000021

The preliminary analysis should be that the previous QSPI programming was unsuccessful, resulting in an abnormal state after power-on and loading.

solution

Change BOOTMODE to JTAG mode or erase QSPI in VIVADO (to select Entire Configuration Memory Device)
