Hi Eric,
About how to program firmware to MCF52234 chip, there are two options:
1. Using P&E PROG-HL-CFZ software with P&E Multilink Universal debugger
P&E provides standalone Flash programming software for ColdFire chip, which works with WIN 10 system.

2. Using CodeWarrior for MCU provided [Flash Programmer] tool with P&E Multilink Universal debugger tool:
Customer need to create a MCF52234 project, then call [Flash Programmer] provided [Flash File to Target] tool.

The File can select customer would like programmed image.

Wish it helps.

Mike
