Hi, I want to load my own FSBL into L2LIM to test my UART driver. I tried the following:
- I created a partition with the type 5B193300-FC78-40CD-8002-E86C45580B47 (FSBL) after the bbl partition (Thanks for leaving some space!). I made it 4MiB large.
- I set MSEL to 11 (0b1011)
- I turned on the board
The result was that ROM1/ZSBL printed “Error 0x0100000000000001”. What does this error number mean?
The manual says “Then, the entire contents of this partition, the FSBL, are
downloaded into the L2 LIM at address 0x0800_0000.” How large may an FSBL partition be? Because it sounds like L2LIM will simply be overflowed if the partition is too large.
