I am Using Cirrus Logic EP9302-CQZ board.
i don't think so, EP9302-CQZ is a processor, not a board, please verify again
The memory address I was talking about was ram address to download u-Boot (as you mentioned earlier it can be 0x1000000) and then perform the actual flash update command by using flash address and RAM addr(0x1000000) from where to pick the image. I am not sure though what value to give to the u-boot size option flag.
0x40000 for size of u-boot is ok
i.e. say on redboot
fis write -f 0x60000000 -b 0x100000 -l 0x40000 Flash addr Ram addr Size <-- how to find size value How to find for a particular board.
so I was wondering if there is any general way to find out such u-bootimage download ram address and size .
if the base address of your SDRAM is 0x00000000 (like on the edb9302 board), than 0x100000 should be ok. otherwise you probably just wrote random values to the flash.
there is no general way for the ram address, it's board specific
Also, if you don't mind can you please guide me with steps to follow in-order to boot the board from UART and to flash the board with new image. Thanks a lot for your kind help.
i repeat, without knowing the board you are using (and find information online if it's not an edb9302 or edb9302a) is impossible.
