Hello :
I am using spi flash
S25FL128S which is made from spansion is in 64KB sector.
My first boot option is serail and second is spi flash.
I have do this test that I use serial to send uboot-spl.bin and u-boot.img to am335x start the uboot ,
then get the uImage from tftp server ,then I use uboot command sf write the uImage to S25FL128S offset from 0.
Then I power off the system ,I use the serial boot the uboot again.
I read the uImage from S25FL128S to sdram address 0x80000000 ,then I can boot the linux kernel bootm 0x80000000.The linux system run fine.
It prove that the read and write to the flash is fine.
But when I write the MLO and u-boot.img to S25FL128S and power on and power off ,the uboot can not boot.
It show five C character then stop.
But when I use the M25P64 write the MLO and u-boot.img to it ,the uboot can be started.
I want to know which spiflash is support by the bootcode in am335x?
Is there any devicelist available?Or how can I start my uboot in S25FL128S by the boot romcode?
Best regards
wangl
