I tested the two major standing problems (USB failure when using DMA and card corruption when using 4-bit bus mode) and they're both still there. Regarding this last issue, I recently had my card corrupted again, so there is a chance that setting the card in 1-bit bus mode only makes the bug much less likely to happen.
Some other in-no-particular-order news:
- Fixed the network mask problem (changed from 255.0.0.0 to 255.255.255.252).
- Rebuilt the whole toolchain and rootfs as MIPS32r1 architecture (was MIPS I). This should result in faster, smaller code. Ingenic doesn't even mention in their documentation that the CPU is MIPS, much less say which MIPS flavor it is. However, Vladimir Silyaev noticed that the Ingenic kernel default configuration is for MIPS32r1, so the toolchain should be too).
- The guys at Qi-Hardware sent me a prototype of their Ben NanoNote device. A post on this soon. They also got a newer patch from Ingenic (kernel 2.6.27), but I'm yet to find time to examine it for fixes that might solve the USB DMA or the card corruption problems (not optimistic thought, because any important fixes should have gone out in their latest "official" 188.8.131.52 patch).
- Some users have reported flash write failures during dual-boot installation. The original SPL restore feature works fine, though. It seems that they have bad pages in the first flash block (which is normal in NAND flash) and the flash write tool doesn't handle them properly. This should be easy to fix, but will take some time because I haven't got an A320 with bad pages.
