CCS for MSC8156_AMC

[Jim95]

Hello,

I try to launch a debug session for a MSC8156AMC board but I always have the same error message (CCS Protocol : Configure chain error).

So I looked at the MSC8156AMC.cfg for the usb Tap JTAG but it looks fine.

I don't understand why it doesn't work, could you help me ?

 I work with CW 10.1.8 and the USB TAP for MSC8156AMC.

This is the ccs protocol log that I have :

My chain configuration looks like ok, so I don't understand why there is an error.

Finally I found problem came that the I2C EEPROM has been erase (address 0X50) so the CCS couldn't find th.e Reset Configuration Words.

I burned the EEPROM with this configuration and now it works.

Hi Jim ,

I am also facing similar problem in MSC8156AMC board , while i am lunching the code its showing unknown protocol ,

i checked in ccs server command " sh cc" which shows usb tab correctly working .

This issue comming on  new 8156AMC board , could you tell me the debug steps you have followed while fixing this issue ?

How to know I2C EEPROM has been erase (address 0X50)  ?

Thanks,

Sunil.

Hi,

To fix the problem I remeber that there is 2 modes to get the reset words configuration : by the I2C EEPROM or by hard coded option. (switch 2.8 on the board)

When I put the switch 2.8 off (hard coded RWC) it works, so the problem must comming from the I2C EEPROM.

It seems to be the same that I had, the reset words configuration was erase on the EEPROM. 

To solve this problem I put the switch 2.8 off and then burned  the EEPROM with the data that I put into my previous post.

Then you can put the siwtch 2.8 on it must be ok.

Regards

Jimmy
