UNIFLASH: Loading image to AM263P4 using SEGGER J-lInk Emulator does not work with 9.3.0.5401

Part Number: UNIFLASH
Other Parts Discussed in Thread: SEGGER, TMDSCNCD263P, AM263P4

Tool/software:

Trying to use Uniflash 9.3 with Segger J-Link Basic probe to program TMDSCNCD263P Rev A board but fails trying to program prebuild SBL image.

Installed SEGGER v8.72a.   The connection seems to be correct (see J-LinkCommander log below).  

When loading program, it complains "AM263PX" (or other variants) is unknown to this version of J-Link Software.

After selecting AM263P4_R5_0, the load proceeded then failed trying to program.

Jlink is connected properly through TMDSHECDOCK and LED on probe is solid green.   Using J-Link Commander, this shows probe is connected properly.

Can an expert help guide me through this process?  I'm not sure where I went wrong here.

Thank you for the support.
