Not having any success with flashloader for '1020...

[EdSutter]

I'm running into a few problems getting started with my MIMXRT1020EVK, so I decided to just follow the steps in the "Flashloader Use Case" document that comes with the flashloader package for the MIMXRT1020EVK (Flashloader_RT1020_1.0_GA)...

Referring to that document and the directory that comes with the package, I ran the following commands:

• sdphost -u 0x1fc9,0x0130 -- error-status
• sdphost -u 0x1fc9,0x0130 -- write-file 0x20000000 "Tools/mfgtools-rel/Profiles/MXRT102X/OS  Firmware/ivt_flashloader.bin"
• sdphost -u 0x1fc9,0x0130 -- jump-address 0x20000400

Each of these commands worked, but the sanity test (as per the document) failed...

• blhost -u -- get-property 1

The USB port is apparently supposed to re-enumerate to a different VID/PID, but it doesn't.

Any ideas?

Turns out that the addresses passed to sdphost are different.  For details on that refer to this post.

In the nutshell...

• sdphost -u 0x1fc9,0x0130 -- write-file 0x20208000...
• sdphost -u 0x1fc9,0x0130 -- jump-address 0x20208400

work much better.  Thanks to the originator of that post.
