Thanks, I've ordered a bundle with the adapter, will take a few days to arrive. I've kept the chip and will report back when done.

Does the 1.8v adapter board drop into the usb boards chip holder? On Thu, 23 Jan 2020 at 09:48, Nico Huber wrote: > > Thanks for the voltage warning. I wasn't aware it was a 1.8v device.

Hi Nico Thanks for the voltage warning. I wasn't aware it was a 1.8v device. I thought it was 3.3v. I guess I'll have to search for another programmer and chip!

CH341A might still be the cheapest option. They are sometimes sold with a 1.8V adapter. Just search for the combination... maybe you can also find that adapter w/o an additional CH341A. The chips might still work, they usually are rather sturdy. Nico ___ flashrom mailing list -- flashrom@flashrom.org To unsubscribe send an email to flashrom-le...@flashrom.org

Some faulty CH341A are giving 5V instead of 3.3V, please test yours with a multimeter. Have you ever successfully flashed any chip with your CH341A? By the way I've stumbled upon two CH341A (two posts on reddit's r/coreboot), one CH341A had a badly soldered chip leg and another was missing a capacitor. Easy to fix, but only if you have at least one working CH341A to compare i.e. the voltages at various points of a faulty vs working one. ___ flashrom mailing list -- flashrom@flashrom.org To unsubscribe send an email to flashrom-le...@flashrom.org
