Hi All. I am having issues uploading the latest firmware. I have full control of the mount via serial but the response from the PMC manager keeps coming back 'Checksum Error on Com5'
Is this a laptop issue or a PMC8 issue. Here is the log from the PMC manager for each of the uploads.

Any ideas?

Regards

Roy

I had the same problem.  Unfortunately I do not believe there is a cure, just a work around.  

1.  There was a suspicion that it had to do with the ftdi or lack of an ftdi chip set.  I had the failure with both I believe .  But I might be remembering it wrong.  If you are using a non ftdi usb-serial adapter then get one with the ftdi chipset.  If you are an iexos it already has it in there, so look at the next point.

2.  What worked for me was to change the pc being used to load the code.  Not ideal I know.  I couldn’t get it to work using my windows 10 tablet.   It did work in a bootcamp Mac air, and it works fine on my Dell laptop.

Sorry man, that’s all I can tell you.   Find another computer.

Roy:

I assume you attempted to update the FW using the Configuration Manager Tool.  Another way to update is manually via Command Prompt.  There are instructions located in the PMC-8 Application Note (AN001).

Thanks Jennifer I will give that a try.😊

Thanks Wes, I have the FTDI chipset and everything else works fine. I’m sure I will find a workaround I just thought I may have a fault. However it’s a computer isn’t it🤔
