Read/Write Flash works.
add this to
C:\Program Files\pgo\USBDM 4.12.1.340\DeviceData\s12z_devices.xml

<device family="S12Z" name="MM9Z1J638">
<clock type="External">

If you have a MM9Z1I638 please share the sdid :)

(Detect Chip and the sdid is in the round brackets as hex)

my is the same

The flash loader does not appear to support EEPROM write operations.

Here a Sample with
USBDM TCL Interpreter

Everything EEPROM Sector has a size of 32 Bit

settarget s12z
openbdm
setdevice MM9Z1J638
reset NH
connect
halt

First - You are my hero :) it's working :)
Secondly, for others: the correct template
(Unfortunately, the engine of this website breaks the code when you upload it as text, you have to upload it as an image, Dennis's template was correct before being uploaded as text)

[Dennis Heynlein]

modification of s12z_devices.xml is sufficient
I have also placed a 470nF between GND and Reset.

[Dennis Heynlein]

The flashloader is not optimal, but it works at first glance.
I am currently trying to adapt the template to the S12Z of MM9Z1J638.
