Forum Post: RE: U-Boot SPL Stuck

Hi Victor,

Download the gel script and load it. This link gives you detail step by step procedure.

After you do "connect target", in css -> "scripts tab" you can see ddr-datatransfer option. If you run that, it will do R/W on DDR for 250 locations. If you want to check all locations in gel script, at line 900, you can edit those parameters. 

Thanks

siva.
