OpenScopeMZ upload failed

[Jiandan]

Dear Digilent engineers

    I found that the OpenscopeMZ board often suffers from uploading errors at such a high baud rate of 1250000. Dear Digilent engineers can give a bootloader with a low speed baud rate (115200).Thanks a lot!

Hey,

We did a lot of testing with the 1250000 baud rate because we were concerned that some USB ports might have problems.  We've described a known issue cause by this baud rate, but it only affects USB 2.0 'Full Speed' ports (remember USB 'High Speed' is faster than 'Full Speed)', and only when transfering large buffers of data.  We have never found this baud rate the be an issue during firmware loading since it uses many small data packets.

Can you provide more details about your system and the USB port you're using?  Have you tried other ports on the same computer and other computers?

Thanks!

Thanks dear Kristoff.

    I do it in WIN10 and with USB High Speed Port.Besides,I test it in other students PC ,but it always failed.

    Now I want a lower baud to test, In order to solve this problem that bothers me.Dear Kristoff ,can you give a bootloader with a low speed baud rate (115200 or others) to test it.Thanks a lot!

Hey Jiandan,

Are you able to upload firmware to the OpenScope MZ using WaveForms Live? 

Thanks!

Dear Kristoff,

    I try to use upload firmware to the OpenScope MZ using WaveForms Live.It is successful.Thank you!

    But  this serial download with problem should be solved ,because using WaveForms Live need net support it that it is not convenience.

In addition,I  try to use he hex file generated by the arduino IDE that after downloading it with the PICkit 3 but it does not work.As you said that the hex file produced by the Arduino IDE does not include the bootloader so programming it to the OpenScope with a PICkit 3 will likely override the bootloader.

 

Thanks  a   lot !

Hey Jiandan,

If you're using the OpenScope MZ with WaveForms live you will never need to program it using the Arduino IDE, MPLAB or the PICkit3.  All firmware updates should be done through the WaveForms Live software.  WaveForms Live is available offline as well and is built into the Digilent Agent (see details in the FAQ under Is WaveForms Live available offline).

WaveForms live uses the Digilent Agent to load firmware onto the OpenScope MZ at the 1250000 baud rate, so the baud rate is not the issue if you're able to do that successfully.

It sounds like the hex file generated by the Arduino IDE is not generated correctly and does not work.

Dear  Kristoff

Thanks a  lot , I tested it several times and found that using WaveForms live would be a little more successful and slightly more successful, but  there would be an update failure too （LED1 OFF）. I  hope that you give a lower baud rate bootloader when you are free, thanks.
