Cannot debug LS1020A board: CCS: Scan timeout(CCSProtocolPlugin)

[qiaofangzhao]

Hello.

We are trying to connect to a custom LS1020A board, but get some error:

Executing Initialization File: C:\Users\qq\workspace\connect-core0\CFG\LS1020A_TWR_Init.tcl

CCS: Scan timeout(CCSProtocolPlugin)

Our target settings are:

Processor: LS1020A

Probe Type: CWTAP

Any ideas? Thank you.

Hello Fangzhao,

There is problem at DDR controller registers configuration, probably it is caused by improper RCW configuration or hardware problem. You need to customize the JTAG configuration file(RCW) according to your custom board.

You also could configuration CodeWarrior initialization file as LS1020A_TWR_OCRAM_Init.tcl to avoid DDR controller configuration, then run flash programmer in OCRAM.

Have a great day,
TIC
