Based on vhdl (actually assembly in mem_arbiter.vhdl) i would assume that fpga.bin is flashed at 0x0, and firmware.bin at 0x60000. Is it correct?
I've flashed and verified the spi using those offsets, but firmware is not booting up. I can confirm that fpga is loaded correctly. All voltages and jumpers are proper.

Hi,

try:

flcli -v <USB ID UMDK> -p J:A7A0A3A1:spi-talk.xsvf

gordon -v <USB ID UMDK> -t indirect:1 -w fpga.bin.bin:0x0

gordon -v <USB ID UMDK> -t indirect:1 -w firmware.bin:0x60000

That is from my notes. I can try it out if you have issues.

Cheers,

Minty.

Yes, I did the same thing and it fails to boot into the firmware. I will check with LA to see actual address and data bus. I can see that FPGA is configured but I don't see any accesses to 0x60000 and up over SPI.

A question: are you using the master or dev branch from the github UMDK repo?

i've tried 20140524 and dev branches. At this point i'm inspecting my soldering. Could be that something is not soldered or shorted.

OK, I have tried both of those too and they work.

Prophet36 gives some advice on the hardware and bring up in this other thread:

Please keep us posted on your progress and we will try to help you get up and running.

Thank you,
do you have any idea what project does cksum.xsvf coming from?

Sorry, I am not sure where that file is. I assumed that it was used by UMDK so I searched the directories of the UMDK project but did not find it.

Could you tell us where you found that file please?

Mmmmm, but I cannot find it in the Repo. We shall have to ask Prophet36.

My UMDK Kit was made for me and I only had to carry out the Unit-Test tests to verify the bitstream written to the FPGA and that the toolchain was correctly installed as the hardware had been checked prior to me receiving it.

The Unit-Tests do calculate expected results and then compare what the MD with UMDK connected returns but that is a step further on than you are at by this stage.

Step #9 is in order to check that the bitstream is correct and has been written correctly but I would have thought that it would fail at an earlier stage during writing and you would see that during the writing stage - what do you get on your command-line when you execute Gordon?

I am not at my MD Dev machine now but I can repeat the steps that you would need to carry out and see what I get and then compare that to what you get but give me a couple of days.

Perhaps send Prophet36 a PM and see what advice he can give.

Cheers,

Minty.

Cksum is part of the early examples provided with FPGALink:

Ok, i got it to boot the firmware, but now chasing another issue:
The SD Card doesn't clock any data out ---
i see the command sent to SD, but no response, not even ACK.
I've noticed that spi_master is coded to be MODE3, but MODE0 is recommended for SD, could that be the issue?
Here is the LA trace -- no response on CMD0 from SD...

Hi,

Prophet36 I *THINK* added the SD-Card support to only the Dev branch - I think.

Have you done traces with your L-A using the Dev and Master?

I would need to check if he added SD-Card support to the Master.

Did you contact Prophet36?

As far as i understand from vhdl and m68k code, everything is in place on 20140524 branch. i can check out dev shortly and will let you know

No i didn't want to bother him yet. I've figured he would've dropped in if he had time.
