Ok. Back at it this morning.
RichAuto Facebook got back to me. They won't help me since I didn't buy the DSP directly from them.
I sent an email to you AllenCNC at the omnisales address, looking for a file that could work to upgrade from.
Recap:
DSP still is stuck on "RichAuto waiting to load..." message when I power up. It had been loading every once in a while if I cycled on/off several times but that has become more infrequent and now I have cycled on/off probably 50 times without it loading in the past few days.
The DSP powers up from both my machine AND from my PC and the emergency startup menu shows up when I use the correct procedure (hold down the OK button.)
When I power up from the PC the PC does not seem to "see" the DSP as an added external device/drive so there isn't a way for me to use the PC to transfer an update file into the DSP. Unless there is and I am missing something.
When i download the 'cleaned and repaired" usb sticks with the RichAuto .pkg file that has the A15s update/upgrade on it the DSP "sees" these files on the USBs but when I try to choose/upload from the sticks i get an error message "file is cracked or broken...."
Should I choose REFORMAT or anything else on the emergency menu? Have I demonstrated that it is the upgrade that is needed and not a new 50 pin cable or the board in the machine?
any other ideas? other resources? I have downloaded and read the manuals. Could it matter that my PC is 64 bit and the machine/dsp might not be??? Is that a thing?
Having too much fun!
