build your own cross-compiler !!!

Hello all,
here’s a Python script for parsing/dumping/building DFU files. I’ve checked the output files with DfuSeDemo.exe, and flashed them to my DSO Nano v2 successfully.

That’s a really great tool! Awesome how you could make it so clean and compact with python. I have a few wishes:

• a list option that only decodes the files but does not write new files
• an option to set usb ID (defaulting to 0483:df11, which most DfuSe loaders already use, makes sense)
• add your name and copyright, and let me add it to the git tree

Tormod, I’ve got a bug report for your dfu-util: the file test_seeed.dfu (combined Seeed v2.5e APP + v2.5 LIB) created from my test_dfu.py works correctly when downloaded to Nano via DfuSeDemo.exe on Windows, but it does not if I download it with dfu-util on Linux. Apparently the LIB part is OK, while the APP is broken.

I have checked the verbose output and I can not see anything going wrong in terms of erase and write addresses. Can you read back the flash memory (using dfu-util -U) and see if it is corrupted somewhere?

BTW, maybe we should make a separate dfu-util thread. There are so many topics in this thread, about everything but building cross-compilers since we dropped that a long time ago
