Re: [coreboot] ?==?utf-8?q? Hardware needed for flashing a T530

[Yannik Catalinac]

Thanks for your answers!

Because I had an 10€ ebay coupon, I decided to buy a CH341A and a 10cm dupont female-female cable for just 0,74€ ;)

Do you know how to check if the CH341A works correctly (like the correct voltage etc.)?

 Hi Nico, please could you confirm that FT2232H (link to which you have
provided) could work as a debug dongle? At "menuconfig" I only see
USBDEBUG_DONGLE_FTDI_FT232H but not FT2232H , don't know how similar
they are to each other

Although there's a problem with
Raspi/Beaglebone/any-other-SBC(single.board.computer)-except-EOMA68 I
have to mention - they're running the non-free binary blobs, and
CH341A or Bus Pirate are better in this relation: CH341A - no firmware
at all, just a few config registers ; Bus Pirate - completely open
source firmware
