I also tried HugeMan’s link “GitHub - Seeed-Studio/DSO_Nano”
On first loading this it showed "Broken option for tool “General” and on compilation throws up 210 errors and 16 warnings.
Many of the errors are from the assembler concerning MOVW, MOVT and MOVS - Error[438]: This instruction is not available in the selected cpu/core.
I can’t see where a different cpu/core can be selected - I thought that was just in the include files.
The warnings are Warning[Pa050]: non-native end of line sequence detected (this diagnostic is only issued once).
Anyway, there seems to be a compatibility problem which I dont understand with this version of the code.

I tested with downloading from the Seeed github link and was able to compile on IAR6.1 without errors. I did get the warnings (Pa050) however and this appears to be an issue with improper line termination (CR/LF vs. LF only). HugeMan may need to look into this as what was submitted to him compiled without hiccups of any kind.

We may also be in for some version confusion now as there are two github sites with Nano firmware sources as well as one Google code site with obvious overlaps. I can also envision it being difficult for a new Nano owner to locate and find pre-compiled firmware and assess what to use. Unless confusion is the strategy here, some consolidation and cleaning up may be in order.

strang, I rebuild the two projects just now,but i found no errors and warnings.
We are considering realease our opensource firmware in github (Seeed-Studio), and we will dedicate to clean up the version confusion recently…as you said.
