Question about firmware on old DM-15CC

Post by HPMike »

I have an old DM15CC Silver Edition that I purchased in November, 2012 that is currently running firmware version 9. It is my understanding that the newest firmware I can install on this hardware is version 16. There are two firmware files listed in the archives; DM15_M1B_V16.HEX and DM15_M1B_V16_32K.HEX, and I assume that I should use the DM15_M1B_V16.HEX file. Please confirm my assumptions and understandings, or correct me where appropriate. TIA.

Well, I've gone ahead and updated the firmware with the DM15_M1B_V16.HEX file, which worked fine. So, I tried it on an older DM15CC that I purchased in July, 2012, which failed with an insufficient flash memory error. I then realized that the DM15_M1B_V16.HEX file is meant for the newer hardware with an LPC1115 with a 64 Kb ROM, and the DM15_M1B_V16_32K.HEX file is meant for the older hardware with an LPC1114 with a 32 Kb ROM. I then tried successfully to update the newer DM15CC Silver Edition with the latest Version 32 firmware. The only downside is that it lacks an RTC, so none of those functions are operable. I should continue to be able to update the firmware in the newer DM15CC, but the older one is stuck on Version 16. Of course, my DM15L will be updatable for the foreseeable future.
