Which board are you using? Minnowboard Turbot ?
SF100 Dediprog is for re-programming the firmware on SPI flash.
JTAG interface is for code debug purpose. JTAG does not work on Minnowbaord Turbot for some reason.
Minnowboard Turbot UEFI firmware provides alternative debug tool: UEFI Source level debug over UART Serial Port.
Yes, I'm planning to use Minnowboard Turbot.
Thanks for the response.
SF100 is enough for getting started.
I've reprogrammed the flash on minnowboards using a raspberry pi and some jumper wires. The flashrom
program on Linux can do everything you need if you already have a pi and some jumper wires.
You should also be able to use the Bus Pirate with flashrom to reprogram the SPI. This is a much cheaper alternative to the DediProg. We plan to document this method at a later date in the TianoCore wiki.
Thank you Zwei4, naikrovek and BrianRichardson.
I wanted to experiment on the firmware. Would like to know, Intel JTAG is necessary for the firmware development or I can go ahead with SF100 Dediprog?
