Dear All,
Can I change bootloader(RBL) scan order first MMC/SD and later NAND?
My board normally nand-boot,
When I need sd-card boot for update nand code,
My board is no key to change boot order(Nand to SD boot)
* BTSEL[2:0] BIT 000 -> 010

My board enviroment
--------------------------------
CPU : TMS320DM368
BSP : Appro IPNC SDK Ver 2.6.0 (not ti-evm)

Can change bootloader scan order 'MMC/SD -> NAND'
----------------------------------------------------------------------------------
1)
In datasheet
DM368 BOOT scan order is
NAND boot fails => then MMC/SD mode is tried
2)
sprufg5a.pdf
166 page
11.1.1 Features
The ARM ROM bootloader (RBL) executes when the BOOTSEL[2:0] pins indicate a condition other than
the normal ARM EMIF boot.
...
• If NAND boot fails, then MMC/SD mode is tried. <----- ****** this order change MMC/SD -> NAND
• If MMC/SD boot fails, then MMC/SD boot is tried again.

Can change DM368 BOOT scan order

Thank you and best regards,
