iMX6Solo Linux patch for development board

Hi,

I'm using the iMX6Solo/DualLite SABRE development board for smart devices. At the moment I am aiming for a system with iMX6Solo and not DualLite. On your homepage there exists a patch that is used to disable one core, thus emulating a iMX6Solo. I do get a little bit puzzled by this patch however since it seems like it reduces max RAM memory size to 512 MB. Is this the maximum RAM size for a iMX6Solo system? If not, why is it reduced to 512Mb in this patch?

Best regards,

Emil

Hi Emil,

i.MX6DualLite and Solo SABRE SD share the same HW evaluation board.

i.MX6 Dualite has up to 64-bit DDR interface and i.MX6 Solo has up to 32-bit DDR interface.

If you emulate an i.MX6 Solo on a Dualite SABRE SD board, you'll be forced to use half of the DDR packages of the board as you'll only have a 32-bit DDR interface (instead of 64-bit) consequently you'll divide the memory size of the board by 2.

Anyway 512MB is not the max DDR size of i.MX6 Solo (4GB max).

Application note AN4397 explains that: http://cache.freescale.com/files/32bit/doc/app_note/AN4397.pdf?fpsp=1&WT_TYPE=Application%20Notes&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation
