David Brownell <david-b@pacbell.net>:
Split out OSK5912 board support from the omap5912 target config, and make
it pass sanity checks on my (Rev C/original) hardware:
- Fix syntax error ("-irlen" not "irlen")
- Provide real TAP ids for the ARM926ejs and the C55x dsp
- Label both CPUs appropriately (DSP, ARM)
- List both flash chips
The scan chain looks like this (note truncated DSP instruction code):
TapName | Enabled | IdCode Expected IrLen IrCap IrMask Instr
---|--------------------|---------|------------|------------|------|------|------|---------
0 | omap5912.dsp | Y | 0x03df1d81 | 0x03df1d81 | 0x26 | 0x00 | 0x00 | 0xffffffff
1 | omap5912.arm | Y | 0x0692602f | 0x0692602f | 0x04 | 0x01 | 0x00 | 0x0c
2 | omap5912.unknown | Y | 0x00000000 | 0x00000000 | 0x08 | 0x00 | 0x00 | 0xff
I still don't know what that third TAP is; maybe an early version of
an ICEpick JTAG router.
