Hi,
I tried to read SPI chip using TUMPA using flashrom under windows10 x64. At first chip was detected with wrong size (wrong id1 0xf0 and id2 0x0022, probably I should have checked driver settings and so on), and then I changed "Buffer Enable" and "Buffer Chip Power Selection" jumpers in different combinations (Yes, I am not so smart and did this when TUMPA was USB-powered). Now the only result I get is id1 0xFF and id2 0xFFFF and SPI flash is not detected, e.g. behavior is the same as chip was NOT connected. Is there a possibility that I have burned the buffer chip? How I can test if SPI_1 port/buffer chip is working correctly?
