Hello,
Thank you very much for ALL the guys and women on this tread !
I have make the flash like that:
This
worked at the first time !
Here's the procedure I used:
- The Motherboard is out of the box with NOTHING on (CPU, RAM, etc. ...)
- Make sure Raspberry Pi is turned off.
- Disconnect pin 8 (Vcc or power) from SOIC8 clip.
- Connect SOIC8 clip to Thunderbolt chip so that it swallows the chip.
- Turn on Raspberry Pi.
- Open Terminal.
- Run flashrom as shown below. It worked the first time.
Code:
pi@raspberrypi:~/Documents/Designare/Mar-28 $ sudo flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=2048 -r Designare-1.bin

- Make sure checksums match on all 3 read attempts.
