Download firmware to ADuCM355

Hi Analog,

I have just received a PCB I have designed with the ADuCM355 on it. I am attempting to flash the chip for the first time, using the mIDAS-Link that was provided with the EVAL-ADuCM355 kit. 

However, when attempting to download the program, the mIDAS-Link flashes green/red (orange-ish) and IAR prints "Failed to get CPU status after 4 retries. Retry?

The debug log is this:

Thu Apr 25, 2019 19:43:36: IAR Embedded Workbench 8.22.2 (C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.0\arm\bin\armproc.dll)
Thu Apr 25, 2019 19:43:38: JLINK command: ProjectFile = M355_Biased_EIS_Debug.jlink, return = 0

Thu Apr 25, 2019 19:43:38: JTAG speed is initially set to: 1000 kHz
Thu Apr 25, 2019 19:43:38: Hardware reset with strategy 7 was performed
Thu Apr 25, 2019 19:43:38: Initial reset was performed

While this issue could be hardware related, I wanted to know if there is anything I need to be aware of when downloading to a clean ADuCM355 for the first time, or if you know what the color/flashing error code on the mIDAS-Link means. I've looked at p. 111 in the JLink Manual but it does not cover the mIDAS-Link LED indicator.

Thanks!
