Re: [ECOS] Reboot flashing from eCos system?

["Stefan Sommerfeld" <sommerfeld at mikrom dot de>]

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".

Bye...
