[0028] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to specific embodiments and drawings.
[0029] Such as figure 1 As shown, figure 1 It is a flow chart of the method for SOC chip to replace its own internal FPGA IP program provided by the present invention. The method includes the following steps:
[0030] Step 1: The MCU IP configures the configuration interface of the FPGA IP through its general IO interface, so that the FPGA IP in the normal working state enters the program download mode;
[0031] Step 2: MCU IP inputs specific command bytes for reading data to serial FLASH memory through its general IO interface, and then enters the starting address where the program code to be configured is located, so that serial FLASH memory can be sent to FPGA IP from this starting address Start to output data;
[0032] Step 3: The FPGA IP that has entered ...
