OMAP - GPMC settings for XIP Memory Boot

Other Parts Discussed in Thread: DM3730

Hello,

Our hardware uses a DM3730 and we are trying to boot using a XIP NOR flash connected to CS0. As per the data sheet, the booting device should be connected to CS0 and mapped to address 0x08000000.

The application note http://processors.wiki.ti.com/index.php/AM35x-NOR-Flash-Support-ApplicationNote, which I am using as a reference, however has a NOTE:

"If NOR Flash is detected on CS0, the address would be 0x00000000 and if NOR Flash is detected on CS2, the address would be 0x08000000. "

I would like to clarify, which of the two is correct.

On Reset, the BASEADDRESS for CS0 (GPMC_CONFIG7_i) is 0x00. Does the ROM BOOT code, set it to 0x1000, if the NOR flash is required to be mapped to address 0x08000000 ?

 

Thanks,

Aditi
