Unable to stat file system/apps/clem.img
--- End code ---

So I get the error "Unable to stat file system/apps/clem.img".
Perhaps this image is somehow corrupted?

But now I'm pretty sure that I'll be able to load image into flash via xmodem.

purpose:
 :-+

frenky:
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: https://github.com/MonsieurV/msk/blob/master/apf9328flash.cfg

# The CPU - mc9328mxl
set _CHIPNAME mc9328mxl
set _ENDIAN little

# There is only one TAP
set _CPUTAPID 0x1092001d

Frenky.

I have just been In my new 289 to check the cap, yours looks upside down compared to mine. Please don't shout at me for being a ***** IDIOT or anything like that. I may/probably be completely wrong. I am a complete beginner electronics wise to you guys so don't know much about these things. The cap looking upside down compared to mine jumped right out at me when I saw the picture of yours.

Hope this helps....

Terry01:
If you wait till tonight UK time I will be able to get a decent quality pic of mine and post it?
