Re: Lenovo Thinkpad L530 Need Bios

It seems that the CH341A doesn't provide enough bower to power the whole circuit, flashing with a RaspPi with a new chip clip finally worked without any issues.

Re: Lenovo Thinkpad L530 Need Bios

May I ask you how you got the flash chip to get detected?
When I'm attaching a chip clip to the SPI flash chip with a CH341a Programmer, I just see RUN LED lighting up constantly. RUN LED is connected to the CS line, so Chip select is active.
This may be due to the Embedded controller being powered by the 3.3V I supply on VCC and jams the SPI bus.
I then tried with RaspPi and if I use piscope to check I/O on the data lines, I see permanent traffic on MOIS/MISO/CLK, so EC jamming the SPI bus may be a plausible explanation.

You can patch EC online (without need to flash) to enable non-genuine battery or battery from older NB series: [url]https://github.com/leecher1337/thinkpad-Lx30-ec[/url]Re: L530 lenovo flashing without bat...-Lx30-ec[/url]
