CWTAP connection failed when using CW to debug LS1088A

[mltom]

Hi,

I am testing our custom hardware based on LS1088A.  We are facing issues with CW target connection.

I am using target initialization files from LS1088A_RDB.

I am unable to connect to the target.

See the Section 7.3 of the CodeWarrior TAP User Guide:

https://www.nxp.com/docs/en/user-guide/CWTAPUG.pdf

Test your connection using the following commands in CCS connection windows:

(bin) 49 % config cc cwtap

(bin) 50 % show cc

Have a great day,
Pavel Chubakov
