DCT2500's

[adrianbv6]

hey guys i know we are not dooing any dct2500's but i came up with this info
www.freescale.com/files/microcontrollers/doc/user_guide/MMC14EBDIUM.pdf

the way i think it is u need a separate cpu board to program those DCT2500's but i am not sure

www.freescale.com/files/microcontrollers/doc/user_guide/MMC14EBDIUM.pdf this device will connect like this ...one side to the DCT2500 board ...one to the individual separate cpu board...other to your computer..
if i am right this DCT2500 will be more expensive to test since u need 2 hardware parts

post any coments and ideas brain storm like i said i am not 100% sure but i think is like that

it kind of looks like the same thing. i don't know what an m*core target is but it also says it can connect to a cpu32 using a 10pin connector, which is the same as the bdm. on page 7 of the pdf it shows the bdm connector and pinout. you might not need any extra hardware just new commands to communicate with it.

VxWorks(R) embedded real-time operating system (RTOS), embedded Internet Protocol (IP) connectivity and the Tornado(R) integrated development environment. The DCT2500 is an enhanced version of the DCT2000--the world's most widely deployed digital cable set-top. Enhancements in the DCT2500 include a faster processor and more memory enabling it to run more robust interactive applications more efficiently

welcome to the forums man lol

ok guys any other boxes that dont have a cpu like motorola version use a jtag


for the 2500 is not that m core target

special jtag for Broadcom BCM7100's BCM7115

difeterent software

similar used in broadcoms for cable modems bcm3310 thats a 10 pin 5 ground other 5 the TRST - TDO -TDI -
TCK -TMS


so for the BCM7100's BCM7115 used in the 2500's may be a little bit diferent as well as the software and addreses but thats the only way to acces the nvram and flash aplications etc.

anyone that can build a jtag for those units and the software post ;D i belive the high defenition boxes and all the new ones dvr bla bla bla all use jtag from now on hey i might be wrong is my opinion so dont kill me

Thanks ADIDCN, That is very good information. Will look at this in the future.

i tried to connect the usbbdm to the 2500 but i get all FF FF FF on the left side when i do reset 1

DCT 2500 must use differen tool. BDM only works for Motorola CPU.

yea worth the try
