DSTREAM not able to connect to custom vybrid board

[abdulnihad]

When I tried to debug application using DS-5 and ARM DSTREAM on custom vybrid platform, it shows

Unable to connect to USB:003604
Failed to read 4 bytes from AP 0 @ 0x40001020 on DAP
Bad argument to command.
Unable to connect to USB:003604.

Can some one tell me what is this error and how can I fix it.

Also When I do auto config in debug hardware configuration tool come with ARM DS-5 bundle, it shows auto config fail.

Even when I try to select platform, there is no vybrid platform available.

Hello Abdul,

please check if the problem occurs also on Tower module.

If problem occurs on Tower module we can help you (we will ask ARM) or you can directly contact ARM (DSTREAM producer)

If problem occurs only on your module, then please check voltage rails, reset circuit and connection of JTAG connector. It could be easy to check it pins are toggling similarly like on tower module.

Hi,

Its working now...There was some problem with reset line.

DSTREAM is also work with vybrid tower.

Thanks for your support.

Hello Abdul,

I am not a SW person but before we dig deeper, have you tried to search the other DS-5 and ARM DSTREAM related threads on the Community, please? - In the upper right corner of the page.

Once in a while, there appear "cannot connect" questions here...

Sincerely, Naoum Gitnik.
