Hi, I have one of the original TAPR Hermes 10 PCBs. It's working very well with the TAPR firmware with PowerSDR and the Apache labs ANAN -10 PA and housing kit.
I want to upgrade the firmware to 10.7 so that I can use Thetis. Am I likely to get any problems attempting this with one of the original boards.
I think I will use the boot loader and insert a jumper on J12.
I am aware that there might be a problem with F3 after upgrade.
I would appreciate any comments and anything to look out for.

Many Thanks in advance.

Hi Roger,

If you open the unit up you might want to put a heatsink on the Ethernet Phy chip.
It gets a lot warmer running at Gige.

Also note that there are later versions of the P2 firmware. Check out this thread:

Also, Thetis will run with Protocol 1 firmware in your Hermes. The only restriction is that you can only use 192KHz sample rate with Thetis and Protocol 1.

Hi, Thanks for the replys, I will do as suggested.

Hi All, Just an update with the upgrade, all went OK with no problems. I used HPSDRProgrammer_web_v0.2.7_windows. Ive been using it for a few weeks so far with excellent results with Thetis.
Also heatsink fitted to Ethernet chip.
Many thanks to all for the comments and help.
