DLP3020-Q1: W25Q64 Flash chips cannot be erased

hello everyone:

    Currently I'm using DLPC120 control program SPI Flash Program to program flash chip。The problem encountered now is that the target device can be identified, but the erasing + programming + verification cannot be achieved, and the error "device verification failed" is reported, Capturing the waveform through the logic analyzer found that the "erase" instruction was sent incorrectly, it should be '0x9f', but the actual capture was '0xb0'。whether it is not supported for this model of chip TI。
