We've been working with the Mistral EVM, so I'm pretty familiar with the procedure by now. But we've moved on to our own board, which is very, very similar to the EVM (different clock frequency, TPS65950 instead of the TWL device and some extra peripherals). It is close enough that I would expect it to work exactly like the EVM.
I'm running into an issue downloading "u-boot.bin" onto the device via UART3 using the "DownloadUtility.exe" that came with 1.0.2, the message says " Unknown error occurred during secondary file download. Please try again"
Is there any way to get a bit more information about what the error might be? Any error logs or anything?
We have verified that OMAP is getting all the appropriate power, the boot mode pins have been set up to be exactly the same configuration as the EVM, verified that all clocks appear to be active. I've 'scoped out the UART3 interface pins and I'm getting nice toggling signals there when the download tries to start. (And UART3 uses exactly the same pins on OMAP as EVM). The OMAP is using Micron PoP instead of the Samsung OneNAND that is on our EVM
Any clues where I might start looking for the issue?
