With ExtraPuTTY I was able to load clem.img into mcu's memory:
load -m xmodem
go -c -n
But When I run "go -c -n" nothing happened so I'm a bit lost here...
Anyway I went into another path of finding all jtag intefaces...
First of ARM9 MC9328MXS mcu. I overlaid pinout from datasheet on the back of pcb to see were are jtag bga pads:
Then I measured resistance to the header on the side of pcb, to find out which signal goes where:
trst tms tdo tck tdi
e37 e36 e34 tp19 tp21
Then used jtagenum to confirm that pins are correct:
ntrst:DIG_6 tck:DIG_3 tms:DIG_5 tdo:DIG_4 tdi:DIG_2 IR length: 4
Starting scan for IDCODE...
ntrst:DIG_6 tck:DIG_3 tms:DIG_5 tdo:DIG_4 tdi:DIG_2 devices: 1
0x1092001D
And yes this is correct id according to this:
