P1011 Custom JTAG config

[juhalaukkanen]

Hello,

I noticed that there is no template jtag chain for P101x target under Freescale\CodeWarrior PA V10.4.0\PA\PA_Support\Initialization_Files\jtag_chains

I need to create custom JTAG config since P1011 based board doesn't work with default JTAG target P1011.

It just gives "CCS last error: Draco/m HIP8: Core not responding" when doing reset or pause after connect.

The board is recognized properly with idcode.tcl script under Freescale\CodeWarrior PA V10.4.0\PA\ccs\bin

So my question is how do I make/generate proper JTAG config file for this target?

Thanks.

Hi,

You may try this:

PQ38 (0x80000000 1)

Attached also.

Have a great day,

CW 10.4 doesn't seem to recognize this target PQ38...

jtag_chain files are used for RCW override feature and this is available only for high-end cpu (e500mc, e5500, e6500). P101x is based on low-end cpu (e500v2) and no RCW is used for cpu/board configuration.

Please provide more details about your board. It is a custom board?

Most probably it is a hardware issue. You should recheck the jtag interface.

Yes, this issue was that I2C boot sequence CRC failed and prevented any communication towards the CPU since it was halted.

Thanks for clearing this out! Now I know it is not about RCW.

Yes it is custom board.

However what causes JTAG connection not to work properly? Connection works with defaults settings really well with P1020 RDB Reference Development Board
