SD read but RomWBW not detecting IDE0

[zomgugoff]

This is a follow-up on the post I made in the RomWBW repo. The IDE device is detected, but IDE0 and IDE1 are not. I read out the serial data from the Pico while it booted and it didn't report any errors. Below is the output. It specifies that IDE0 is open, but RomWBW says "NO MEDIA" for IDE0. When booting the RC2014, IO is logged also.

Sorry, but as I mentioned on the WBW issues, I have no way of testing this I don't have a machine capable of running WBW with the interface.

Does the SD card interface work with a stock RC2014 build ?

Hi @zomgugoff,

Could you please post your rc2014.ini file? I will try to replicate your issue.

Thanks, Wayne

[zomgugoff]

I have not tried a stock build. I can try it. I will post my INI when I get home. I can say it's unchanged from the WBW INI except for fixing the image filename (because the archived filename is slightly different)

[zomgugoff]

@wwarthen Here is my INI

#
# RC2014 ROM WBW configuration #
#

[IDE]
#file to use for IDE drives;
idefilei = "RomWBWIDE.id";
iscf = 0;
idefile = "hd_combo-RC2014 Zed.img";

[DEBUG]
trace=1;

#for other settings see README

[wwarthen]

@zomgugoff, your rc2014.ini matches mine (except I don't have trace enabled). This configuration is working for me. I'm not sure what to suggest.

[zomgugoff]

Do you have any output with trace enabled I can look at? I would be curious to see what I should be seeing. Also, if I were to make my image file available, would that be worth testing?

[zomgugoff]

@ExtremeElectronics I only have the 512K RAM/ROM board. I don't think I can run stock ROMs. But in the most minimal config, It's still reporting no media.

[wwarthen]

@zomgugoff, I captured this log file showing the initial power-up of the board followed by RomWBW booting.

boot.log

Thanks, Wayne

[zomgugoff]

Aha, I see only writes in my output whereas you have reads and writes. I'm afraid I don't know enough about the Pico nor the RC2014 to discern what is to/from on those lines, but obviously, I've only got 1-way communication. Thank you for doing that.

And now, I will reveal a simple case of user error:

I started re-poking the solder joints and found a short between GPIO14 and GPIO15. In the process of tracking this down, I attempted to remove RN2 (where I initially found the short) and broke pins 2-6 off. They were still in the board, so I reattached the remaining legs and at the very least, IDE0 is now detected.

I apologize for the run-around in tracking this issue down. I now have to make an 'order of shame' for a new resistor network.

Thanks again for putting up with my self-inflicted issue.
