We are now working on a solution which involves booting a system from NOR flash. We tested NOR flash boot on DM8168 EVM(Rev E), with the daughter board.
We did the following setting according to the U-boot PSP guide doc.
SW3-->CS0BW On
SW3-->BTM[4:0] ==> 10001 (or 10000)
SW4 ---> NAND OFF
SW1(Daughter card) --> SW1[3:0] -->0011
And we built a nor-booting-oriented u-boot.bin and flash it to the very beginning of the NOR flash.
Here's the issue. After all is done and set, it seemed 8168 could not boot from NOR flash, ie, no characters are sent through UART. But we DID successfully recognize the NOR flash after we boot from SD and have a Linux environment.
We are using uboot version psp04.00.00.10. Did anyone encounter the same issue? Any hint might be of great use to use.
Thank you all in advance.
