Hi,

This is Kotteeswaran from Prevas India.

We bought USB Wiggler for imx6 from Macraigor, we are planning to use OCD Commander for our

debugging

I did the following:

I have created MACRO file to initialise the DDR3 and then I loaded UBOOT elf file,

It is showing Memory Read Error <DDR3  Memory address>

We have used BDI3000, we can debug it and initialise DDR3 without any issues,

we would like to know what is the issue with OCD commander?

I understand we need to create Macro file for initialisation OR Is there any way other than this, to configure RAM using OCD commander.

Please reply ASAP.

Thanks,

Regards,

Kotteeswaran G S

Hi Kotteeswaran

first you can check Chapter 7 "Configuring JTAG Tools"

i.MX6 System Development User’s Guide (rev.1, 6/2013)

http://cache.freescale.com/files/32bit/doc/user_guide/IMX6DQ6SDLHDG.pdf

and check by oscilloscope jtag signals. Are you able to access internal RAM,

processor registers ?

Best regards
