I figured it out. The problem wasn't timing with the service, it was problems with an old version of U-boot on a different board than I had been testing with. I updated U-boot (like I had to do on my testing board) and it all works now.
That said I still don't fully understand the problem. Where is U-boot stored? I'm booting from a microSD card and using that card in one board works, but didn't when I switched to this other board. Does it not pull that data from the microSD card? Is it reading from the eMMC of the other board?
