The iFlash Solo, in my experience, is not compatible with Rockbox on an iPod 4G. This may or may not depend on the specific SD card you use as well – I don't know. You can get it to (barely) work by messing with the timings, but for me it was never even close to reliable.
I've had the best success using compact flash cards. The ones I've used essentially behave the same way as hard drives using Rockbox on an iPod 4G.
One last point: in my experience, you'll eventually run into trouble using Rockbox's DMA on iPod 4Gs regardless of the hardware used, i.e. even using a hard drive, so you may want to disable that to prevent disk corruption in the long run.

I built Rockbox 3.14 without DMA as you recommend but it did not help. Didn't really expect it to help with SD-CF adapters, but thought it was worth a try.
I also tested a Tarkan CF adapter board meant for 5G ipods ("iFlash CF"). (There is yet another adapter to make it fit in a 4G.) Same result as el cheapo: Apple firmware works, but Rockbox crashes. Plugging in USB locks up the Rockbox UI and a panic happens a little while later. A tiny wrench? icon appears in the upper right corner. Without USB connected, attempting to browse files also hangs the UI with the little wrench icon in the corner.
Finally, I gave up and put an old Toshiba 20GB drive in. As expected, Rockbox works perfectly.
Too bad big CF cards are getting expensive these days. :(

It's been a number of years now, but the Tarkan CF to SD adapter was a better fit for my iPod 5.5G at the time than one the cheap knock-offs. Among other things it had a 128GB limit on the file system (the Tarkan does not).
Sometimes it's better to just spend the extra money. Actually going through this in real time with another device and me being cheap and not sucking it up and buying a full ZIF-based SSD.

It's not just the expense, but the pata-based CF cards also don't seem to go above 256GB these days, with no signs of larger capacities arriving anymore. Bit of a shame. :-\
