it's just a list with an applied rs232 filter, DigiKey has tons of 3 pin UART cables as well. -vb On Mon, Mar 5, 2018 at 8:22 AM, Nico Huber wrote: > On 05.03.2018 17:06, Vadim Bendebury wrote: > > Did you consider one of these: > > > >

Thank you for your results, Georg! Although this "adafruit board" costs twice more ( $15 ) and has a microUSB instead of a sturdy full-sized one, your report gives me more confidence in the success of the idea. Perhaps this information could be somehow included to the coreboot wiki, especially to

These digikey cables do not explicitly mention that they have FT232H chip, also they cost $23.5 minimum while aliexpress board costs $7 - 3x times less expensive On Mon, Mar 5, 2018 at 7:06 PM, Vadim Bendebury wrote: > Did you consider one of these: > >

Did you consider one of these: https://www.digikey.com/products/en/cable-assemblies/smart-cables/468?k=ftdi+uart==ftdi+uart=316=ffe001d4=0=0=1=25 there are many options, it is important to match the cable's VDD to your board's (1.8V vs 3.3V), the rest of the parameters is way less important.

Hi Kyosti, Thank you very much for your reply! I will try to get a couple of these FT232H boards: perhaps just 1 is required for the successful setup, but these boards are not common (just 15 or 20 search results) so maybe its' a good idea to take 2 ;) If this FT232H board works, it would be an

[coreboot] $7 cheap FT232H board as EHCI debug dongle for coreboot - would it work?

Good day! I am looking for the dirt cheap EHCI debug dongle. Initially I found these instructions for FX2LP - https://www.coreboot.org/DIY_EHCI_debug_dongle - but they require a lot of manual soldering/mods which depend on your boards revision and I am not sure if the currently produced boards are
