Unable to flash using JLink and SDK

I’m having an issue flashing an image onto our DA16200. I see that SDK has a big change to JLINK loaders as well as the programming address of the bin files.

It appears that loader files from SDK don’t work. I’m able to connect to the chip but unable to erase it. If I use the loader from SDK, I’m able to connect and erase the chip.

SDK erase DOES NOT WORK. I'm using JLink 770.

/Applications/SEGGER/JLink/JLinkExe -Device DA16200.eclipse.4MB -Log "./jlink.log" -CommandFile "erase_all.jlink"

Results in:
