I am absolute beginner but I need to read and write the above mentioned serial Flash memory.
This is a BIOS chip and had a bad flash. Now it is unsoldered from mainboard.
How do you connect the buspirate to the chip and what is the chip's form factor (e.g. soic8)? The datasheet mentions SOP/WSON/PDIP.
I want read it out and reflash a new BIOS file.
Therefore I really need help how to connect the chip pins with the buspirate pins in a correct way.
This is how pins are shown in the data sheet of Macronix MX25L1605DM2I-12G
CS# 1 8 VCC SO/SIO1 2 7 HOLD# WP#ACC 3 6 SCLK GND 4 5 SI/SIO0
This is how I connect my buspirate to a MX25L1605A soic8 chip:
CS# (CS) [1 8] VCC (bridge with buspirate pin 3+7) SO (MISO) [2 7] HOLD # (+3V3) WP# (bridge with buspirate pin 7+8) [3 6] SCLK (CLK) GND (GND) [4 5] SI (MOSI)
I am using Bus Pirate v3.5 with FW v6.2-beta1 r1981 BL v4.4 and flashrom v0.9.6.1-r1624 on Windows.
HiZ>i Bus Pirate v3.a Firmware v6.2-beta1 r1981 Bootloader v4.4
Would I have to setup the buspirate in a terminal before using flashrom? I mean SPI mode and so on? If yes could someone help me with this settings too?
It's not necessary to change modes (no need to change from HiZ to SPI).
