According to the Xilinx official guidance document 1078, 1079来 debug amp Mode boot more laborious, because already very old tutorials. In fact, the whole document is useful for just a few points. Summarize the implementation on a few lines of code. In order to make the majority of code friends easily implemented, the close-up method is as follows: The first step: Create Zynq FSLB Common Engineering, and then add the LOADCPU1 code in main. void LoadC

Ipvq7000 series chips have 54 mio, which are allocated to bank0 and bank1 in the ps section, which are directly connected to PS. Note that the base address of the gpio operation is 0xe000_a000.
