That's math, ijs.
I'm glad he counted and realized that the 3rd party site was wrong. @balanga should consider contacting the poster, and update the OpenWrt Wiki as suggested.
You'll learn, I told him to count because:
- I don't own the device
- I didn't write the instructions
- And actually, I told him to count in multiples 0x400, just as you did
- I wasn't going to guess an arbitrary flash address for him (the instructions' poster should have been accurate)
Just a BTW.
