I'm learning how to use the ccs tool with a ls1021atwr board. I currently boot with no core running, and I use ccs to release core 0. In all the documentation and all the question on the forum I read, I see the following command to write to a memory mapped register:
ccs::write_mem <chain_pos> <addr> <size> 0 <data>
However this always returns me a "Scan timeout" error. If I use 1 instead of 0, the write seems to be correctly performed.
The 0 is named "space" in the documentation, but I can't find any information about it.
1) What is this argument for ?
2) Why is 0 failing ?
2) Can I safely use 1 instead ?
