bpod- matlab problem

sandraromerop

Hello,

I have a new bpod (r0,9), and uploaded the corresponding firmware (_0789) using the Arduino software , exactly as it's indicated in the wiki (selecting the COM_X in the native USB , connecting the bpod to the programming port). The operation appears as successful when it finishes.

This computer has already run protocols through bpod, the only thing I'm changing from the setup is the bpod itself,.

But: when I try to use the bpod I encounter the following:

- When I start bpod, always the first time I call 'bpod', it doesn't appear to find the bpod connected. If I do a consecutive 2nd time, then it find the bpod in the correct COM port (this happens everytime I start Matlab),
- When I try controlling the water valve directly through the console, there's no
- When I try running a state matrix, I have the following error:

Error:invalid op code received
Error:invalid op code received
Error:invalid op code received

Error in RunStateMatrix (line 116) NewState = GlobalCOunterMatrix(BpodSystem,CurrentState,CurrentEvent(i)-45)

Thanks

Hi Sandra,

As per the instructions, you shouldn't use the programming port.
Select "Native USB" from the "Ports" and "Boards" menus, and plug the USB cable into the port labeled 'USB' (this is the native port).

If a firmware upload using the native port fails, the board will be bricked until it is rescued using the programming port. In this case, select 'Programming Port' in both the "Ports" and "Boards" menus, and plug the USB cable into the port labeled 'P'.

If you still have trouble after uploading, please paste the text from the black window in the Arduino UI to the forums.

Thanks!

Hi josh,

Thanks for the answer. I tried resetting the bpod and uploading it through the USB native port . The operation appears as successful but I still get the same error in Matlab and can\'t control the bpod. I didn't understand how to 'rescue' the bpod. I plugged it through the 'P' port and selected the programming port in the Arduino software. Then uploaded The files again but got the same error.The black screen that appears after the operation in Arduino is in the link below.' pid='591' dateline='1529065819']

Thanks

Hi Sandra,

If the upload was successful with both native and programming port, I don't know why you're seeing this issue. Please contact me at support@sanworks.io and we can arrange a remote desktop session this week to debug the problem.

Thanks,
