[0034] 1) First create a text document and input the commands to be tested. If there are multiple combinations, you need to input them on separate lines. The format is two-byte hexadecimal numbers separated by spaces, arranged in sequence, and press Enter after inputting. new line. Such as:
[0035] Write command 0x02+column addr+data
[0036] Read command 0x03 / 0x3b / 0x6b / 0xeb / 0xbb+column addr+length (two-byte hexadecimal)
[0037] 0x13 / 0x10+block / page addr
[0038] Erase command 0xd8+block addr
[0039] 2) After the script file is input, open the Debug Tool, click the Scan button, openFT4222device, and then set various flash parameters and test conditions on the interface, click the loadfile button after completion, load the command file just created, pass Programming calls the library function of FT4222 to realize the test work of SPI NAND Flash.
[0040] 3) The running result is displayed in the blank area on the right, and at the same time, the correctness of the comma...
