Goodday,

I am having problems with the programming of a custom pcb which is using an atsam4sd32c. I am unable to program the microcontroller trough the JTAG/SWD interface using the ATMEL-ICE debugger. However i am able to get the device signature identifier using the atmel studio 7.0 command promt. doing manual chip erases and resets is also possible.

When i try to program the board via the atmel studio 7.0 software the upload hangs at 14%.

We have tried a lot but not progress is being made.

Can anyone help?

Thanks in advance,

Maarten Roozendaal

Hello,

 

Probelm solved!

 

The problem was in de hardware design of the JTAG lines. I was unaware of the need for pull-up resistors on all JTAG lines (TMS, TDI, TDO, NRST and TCK).

after we applied the resistors programming worked fine.

 

greetings,

ps. the following design quide (page 8 and 9) helped me out: http://www.atmel.com/images/atme...
