X-SW-Source: 2005-08/txt/msg00149.txt.bz2 Hi, coming back to this, because i really need a solution. I tried to load a RAM based RedBoot out of my ROM based RedBoot without any luck. Is there a way to build a "CYGSEM_HAL_USE_ROM_MONITOR" RAM based RedBoot? I made a RedBoot which allows me to flash the first sector, but it reports: "Sorry, 'RedBoot' is a reserved image and cannot be deleted".
