Debugging LS1046 DDR4 with tools codewarrior

My board NG in BL2 init step.so I try to refer "QCVS_DDR_User_Guide" Debugging LS1046 DDR4 with tools codewarrior.

I saw a DDR struct "ddr_raw_timing" in my atf project ddr_init.c and it also appears in the document "QCVS_DDR_User_Guide: Click the Generate Processor Expert Code icon. ddr_init1.c".

but nothing happened when I click the Generate Processor Expert Code icon In my ls1046 CW project, and just have this files:

Am I using it incorrectly?

I haven't used DDR validation yet. codewarrior.whether it needs JTAG debugging?

Thanks

Hi @Hmc510

Looks like your ddr-init code is generated successfully.

What tools are used to connect 1046 boards? Please provide the purchase address?

You can use Codewarrior TAP to connect with board. Below is a link

DDR validation in codeWarrior, does it need to purchase additional licenses?

The validation feature of QCVS is licensed as per the CW4NET licensing tiers.
To purchase a license, use the link, www.freescale.com/cw4net.

Thanks
