Are the dipswitch settings correct on the bitstream upgrade section? 'sw6 dip2 off' is contrary to this: https://bitcointalk.org/index.php?topic=94317.msg1073047#msg1073047 which shows 'sw6 dip1 off'
It looks correct as per the settings here for the 1.5 controller:
http://www.enterpoint.co.uk/cairnsmore/cairnsmore1_support_materials.html
'3' (a.k.a SW1-3) is programming enabled, '6' (a.k.a SW6-2) is SPI programming enabled
I'm referring to the section for upgrading the bitstream though, not updating the controller, is the SPI switch still relevant at this point in the procedure?
And is SW6-1 baud rate? because I'm getting better results with that set to 'off' or 115200 for mining.
The guide is excellent btw
Yes, you're right. I got those transposed somehow.
I've corrected them to leave SW6-1 off (115200 baud) all the time (there's no reason to change it when flashing)
For controller programming, setting SW1-3 & SW6-2 off is only necessary when reflashing the controller post 1.3 so that's a good catch-all
I've corrected the FPGA programming settings as per Lethos's diagram
Well spotted, cheers for that
- I'm not in a position to do a full dummy run of this as I've got a single board happily hashing away and don't want to interrupt it....Well I was kind-of right..... if you consider being wrong as right that is.... thought I'd better check the info.....
Switch SW6-1(also referred to as 'switch 5') is the board array clock rate not baud rate (heh) and it sets the array clock speed between 50mhz and 100mhz on enterpoint's controllers and 25/50mhz on Glasswalker's. I got confused while setting the baud rate flag in Cgminer probably.
