I'm using the same patch on a ep93xx based board using P30 flash. Works great for me. The only problem I found in the patch is in flash_hwr_init() the first: + __strata_info.base1 = (void *)CYGNUM_FLASH_BASE; Should be removed. The __strata.info is only available #ifndef CYGOPT_FLASH_IS_BOOTBLOCK. The .base1 is actually set correctly a bit later in the code. Regards, Hartley
