Reading chip failed
I tried reading a ST93C46C chip using ICSP:
$ sudo ./minipro -i -p "ST93C46C(x16) @SOIC8" -r data.bin Found TL866II+ 04.2.86 (0x256) Warning: Firmware is out of date. Expected 04.2.99 (0x263) Found 04.2.86 (0x256) Reading Code... 0%IO Error: Async transfer failed.
It seems that this chip uses Microwire, which is SPI with different timing and latching.
I triple-checked the pin layout, it is correct. What could be the cause of this problem, and how can it be fixed?
