MIPS ejtag

[razorx]

I got some problems with my mips/bcm based satreciver and i was wondering what cabel/wiggler i should buy? I need to readout the eeprom and the bcm chipp contents. The reciver has a "standard?" ejtag port with 14 pins.

Hi, you could use the wiggler jtag, but you need to customize the pin configuration.  The wiggler we provided has a standard 20 pin header.

thanks

Ok Mike thanks for your help! Im getting sick and tired of soldering/resoldering my own jtags.. Hopefully this will fix my problem now. What kind of software do u recomend that i use?

Hi, you could try openocd.

Actually, I am recommending the cheaper one, the universal jtag, you can try it first, it should work as well.

Thanks

i did order the wiggler it might come in handy for future use i hope

Razorx,
Im modifing tjtag to work with the new Universal jtag, testing it as we speak and have added support for a couple new pins. It's a great little adapter, very customizable. Please let me know what outtput you get from whatever adapter you get, what processor and flash chip  does it have exactly? just provide some feedback, and I will try to help if you need it.

[razorx]

The cpu is BCM7325, the flash im not sure but i think its a NXP chip. I can send you a highres photo of the reciver if u want?

*edit* TDA8024T is the NXP chip number

Havent recived the wiggler yet, but im patiently waiting

[tornado]

Which one did you get ? can you provide a link to it ?

Thats the one o got/ordered

Ok, yes I know this adapter and have one myself, but if I were to recommend a adapter, it would be the new Universal Jtag Adapter, I have been writing the next version of tjtag that will make it a little less problematic. I am writing code to work with this adapter. In my opinion, it is a low cost, highly customizable adapter, that will work with Tjtag, openOCD, and UrJtag..., the best low cost adapter out there. If you decide to purchase one, Please use my referral code - TJTAG

Now, when you get your adapter, let me know, and I will try and help you with that board.

P.S. The adapter has a special price now until the end of January.
