Hello,
I'm trying to start DM8168 on our designed board with NOR boot via GPMC,
but still failed to start.
I've prepared the related environments for build and firmwares following the informations shown as below.
http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_PSP_U-Boot#NOR_Support
Now, my recognization is that the base address of NOR Flash is 0x08000000 and DM8168 tries to read from this address.
But it is seemed that DM8168's GPMC on our board does NOT read above address correctly.
I guess that GPMC[26:12] are not assigned as the different purpose from GPMC as the default,
and if these pins are all fixed to pulled-down internally, the GPMC can read 0x08000000 correctly from the NOR Flash side.
But if the pins are not all fixed to pulled-down successfully in the DM8168,
the bits which are shown by these pins may be 1 and then the GPMC tries to read the different address from 0x08000000.
My question is that whether do GPMC[26:12] of DM8168 have the status High or Low when power-on reset ?
And if they have High, what address should the u-boot be placed in the NOR flash ?
Best regards.
