Preparing the Hardware/Bootloader:

There you get informations how to use a similar Winbond W90N740 based router as cheap ARM7 development platform. I think they discribe the DN-11004-N as "REV2" with broken JTAG access. After some tests i have found why the JTAG is not working and patched jtagger. Now i have successfull done all Hardware mods to my router and installed the new bootloader and the uClinux example image.
