I'm trying to add support for Kinetis KS22 (currently comes back as
unsupported SSID 0x22000418).
The DIEID (0b01000) doesn't match what the reference manual says it
should be (0b10111) and I've asked a question on NXP about that.
I've added some code to kinetis.c (see patch below) to recognise a new
DIEID (0x400) to treat it the same as a K22 and can connect.
As suggested by Tomas on IRC last night, I can read SIM_SDID which confirms:
Open On-Chip Debugger
> mdw 0x40048024
0x40048024: 22000418
I can't flash anything, I guess because I've got no banks set up.
> flash banks
#0 : MKS22FN256VLL12.pflash (kinetis) at 0x00000000, size 0x00000000,
buswidth 0, chipwidth 0

Any advice on what else I need to do to kinetis.c would be appreciated.
Regards
Chris
