Hi, I’m trying to get back into this stuff and after having completely failed to find a place to buy a new fez I’ve dug out my ancient cobra but I’m having real trouble getting my older cobra updated to use all the new things.
There doesn’t seem to be a legacy page specifically for this board but I think this is an EMX based cobra.
Plugging in via usb produces a device who’s drivers I can’t find, tried to install the netmf 2016 sdk but it fails. I got it into usb serial boot mode but the device cannot start (Code 10), the forums seem to suggest all sorts to fix this but I’ve not been able to get any of it to work. I’ve tried the non-default drivers (as linked on here) but they don’t work either and any disconnects cause my machine to hard crash. I’ve tried using com1 and the lmode pin down with a ftdi board but nothing is ever returned over com1.
All this is me trying to update to the new bootloader. Which I /think/ I need to do?
Anyway, would be great if anyone has any suggestions as to what I need to do to get this thing updated and running again with tinyclr.
I’m running on windows 10, tried usb 2 and 3 ports, various hubs. Any help would be greatly appreciated.
I’ve already tried using the com1 serial option. I have now tried again. I can get no response from of com1. Can you please tell me the settings I should be using to talk to com1? I have tried to use both a ttl ftdi and usb serial port. Both of which work with windows 10. I’ve wired the ttl ftdi into a loop to ensure the terminal was functioning and it was.
The instructions are also a little unclear as to how I’m supposed to get the bootloader to use com1. LMODE seems to do nothing. Can you please give me specific instructions for the EMX?
I will absolutely pick up a new fez when they become available but I have this 7inch tft that goes with the cobra and I’d love to get some use out of it.
I clicked the link and loaded the whole web page. It does not say anything about using com1 instead of the usb serial port. Another page says that I should be pulling LMODE low, which I have tried. But not what other combination of pins are required for getting it to work. LMODE alone does nothing, but then with 3/7/53 it seems to do nothing either.
What serial config do I need to use to talk to com1?
What pins must be held low to get the com1 port working?
Is ttl acceptable for talking to com1 in this mode?
Thanks in advance for your help with these questions.
