Hi , I'm using EVM6446. I know I can use JTAG to finish this work. But I don't want to use JTAG to burn uboot into Flash, I want to burn uboot via "ttyS0" (serial port).
I mean:
I want to write an application in PC host (Linux), in this application I want to "open" ttyS0 and pass uboot.bin into Flash on EVM.
1) In this application I think I can open "ttyS0", but I do not know an exact memory address of Flash on EVM board, so I don't know where I should write "uboot.bin" to.
2) Even if I know the address of Flash on EVM board, how can I tell EVM " now I want to write something in the memeory address?
Could anyone tell me what I should do or some references?
Thanks.
