I am starting a new design and want to use a SPI flash for the RCW, PBI and to hold a u-boot image. I have set up the cfg_rcw_src[0:4] hardware pins and now I am filling in the 512 bits of the RCW. The PBI_SRC is set to 0101b for SPI 24-bit addressing but I am confused about the BOOT_LOC field as there does not appear to be a SPI option. I would like to know what I should use for these 4 bits so that it boots properly.
I have examined the start_here.html document in SDK v1.2.3 which seems to outline what I would like to do but details are sparse on how to generate the PBL image to do what I want.
Any help on this is much appreciated. Thanks.
