I see various comments about not building in Windows (taken). That Segger j-link hardware is not very well verified with open OCD (per posts.)
Who’s might be the best for 1.45 V core 2.2 volt pins i.MX27. (ARM926ejs v5) This means you need adjustable voltage and transceivers. BDI-3000 works great but for $2000 it should.
Flyswatter or ? the flyswatter has a open schematic so I know the voltages will be ok as with the BDI-3000.
