It's been ages since I last made a post, I'm sorry about that!
The WM8505 machine I've got has a few bigger issues than just u-boot. I've managed to confirm that I've broken w-boot too. This means that reflashing with JTAG without knowing the physical memory map of the chip is actually impossible. Therefore, I'm going to remove, re-flash and resolder the 4Mbit SPI chip.
I'll keep you posted as to how it turns out!
In other news, I'm getting to grips with SPICE circuit simulation, which is rather fun. If you're at all interested in that sort of thing then please check back soon, as I'm thinking of writing a few short tutorials. Let me know if you'd like that!
EDIT: Grammar
