JTAG schematics

JTAGSchematics — Tue, 27 May 2008 10:32:31 GMT

Hi,

I'd like to know if it's possible to someone inform me where can I get schematics for JTAG interface.

I've got to program a 56F8013, could someone help me with some schematic?

Are those schematics, found on Evaluation Board manuals, valid? (Those that use some buffers and are pluged in the parallel port)

Thanks in advance,

Northon

Hi,

I checked with my colleague working on the hardware team.

You can use the schematic from EVMs manual (8367EVM for example).

Also the parralel jtag converter is described in flash_over_jatg_v2 manual (faq-19720)

Hope this will help you

Hi,

I'd like first to thank Pascal for the help he provided, I'm studying the schameatics he suggested and it's the one i needed. The thing is that, while I was analyzing it I've found some things there that i coudn't understand. There are two CIs (74HC244DW and 74LCX244DW) that have their pins 7, respectivally, connected to a box with a number 1 wrote in it. I just can't understand what that means.

If anyone please have sometime to check it out and help me, I'd be thankful.

Regards

I think the square with a 1 in just represents a Test Point or pad.

I adapted this attached schematic for a simple 56F8013 and it ran out.

It works fine.
