I use BDI to debug these two instructions. And here are the output of BDI
just before the "rfi". The content of R6, R7 is different from SRR0(SPR26)
and SRR1(SPR27).
cds8548>res run
- TARGET: processing user reset request
- BDI asserts HRESET
- Reset JTAG controller passed
- JTAG exists check passed
- IDCODE is 0x0003901D
- SVR is 0x80390011
- PVR is 0x80210010
- CCSRBAR is 0x0_ff700000
- BDI removes HRESET
- TARGET: Target PVR is 0x80210010
- TARGET: resetting target passed
