Access boundary scan chain through j-link

devlin · January 11, 2008 at 6:14 PM

Hi,
I would like to use the j-link to access the boundary scan register in an ARM9
processor (atmel at91rm9200). Is this possible somehow ?
I can't find anything specific about this in the SDK documentation.

The purpose of this would be to verify the CPU pin in/outputs.

Thanks
Devlin

Hello Devlin,

you can use the JTAG API functions such as
JLINKARM_JTAG_StoreData() JLINKARM_JTAG_StoreInst() and JLINKARM_JTAG_StoreRaw() etc.

If you have the SDK you should have everything you need.
