Greetings!
I've been using a mesa plug-and-go 6i25 with 7i76. Everything worked as advertised. First time!
Seriously, folks... The 7i76 drives my steppers just fine, and now I need to add a 7i77 servo daughter-board to drive an analog servo amp, so I needed to update the firmware.
Mesaflash didn't work, so I compiled it from source. (I had to fix some sizeof() warnings and take out some 'inline' tags to get a clean compile. Seems like it shouldn't be that hard.) Then I tried to download the firmware:When I do
sudo ./mesaflash --device 5i25 --readhmid
and it shows stepgens on both P2 and P3, so I'm wondering if perhaps plug-n-go kits' pre-loaded firmware is write-protected?
How do I download a 7i77_7i76 config onto my 6i25?
Thanks
Reid

DID you jumper for the writing
look in the pdf to see jumper settings

You should use the latest mesaflash from
github.com/micges/mesaflash/tree/v3.3
it looks like the old mesaflash may have corrupted the boot block
so make sure you re-write the firmware before cycling the power!
(note: there are no jumper settings related to flashing the 5I25 firmware)

If you're going to make one mistake, you might as well make them all, I always say.
Fixing the jumper helped too.
Thanks
