i.MX6 UL: loading image on OCRAM using Mfg tool

prabhatkumar — Thu, 01 Dec 2016 20:33:38 GMT

Hi,

I am using i.MX6 UL EVK dev kit. I was wondering, how to load u-boot image on OCRAM using Mfg tool. I can't find any document related to this. I would like to test this on the dev kit.

Hello

We do not have OCRAM image of U_boot, at least because

of size : U-boot takes about 400 KB, OCRAM size is 128 KB.

Have a great day,
Yuri

Thanks for the quick reply. Is it possible to load a piece of code on OCRAM using manufacturing tool to get the board from brick to configured state? Then I can use the configure state to load image on External RAM or other boot devices.

Hello,

    Yes, basically it is possible to load a piece of code on OCRAM using manufacturing
tool. At least two points should be taken here for careful considerations :
1) loaded image should contain the IVT ;
2) OCRAM in itself used by boot ROM during load, therefore
   only area, mentioned as "OCRAM Free Area" in i.MX6 RM, section
   8.4.1 (Internal ROM /RAM memory map) is available for application.

u-boot.bin and u-boot.imx

Also, please look at "Manufacturing Tool V2 UCL User Guide.docx" in MFG documentation.

Regards,

Yuri.
