Haha, I was wondering why you were only writing 1 byte but reading all 4. Cooleo.
First post: "0x007CE020" points to "0x5193BD6C"
a few posts down you added the picture about the new error:
1-5193BD6C
2-799864E0
3-746F686C
4-1
since you gave the same addr twice (first post, then a day later), I assumed it was static: my error. (?)
Glad it's all working.
