Always choose the latest version . the bugs are fixed and new device supports are added . it will make your task easier. > > - what bootloader can you recommend to choose for porting on the > board?

I briefly check the Web Links and found that only U-Boot > supports ARM9, am I right? since the board is ported to uCos it should be using the reboot as default bootloader. so you can use the same. insted of porting it. reboot supports linux too. just port the linux and run it over the existing redboot. mostly you may not need to change the bootloader. > > - I mentioned above about uCos - is it reasonable trying to port uCos > device drivers on to the Linux platform, or drivers should be > rewritten from scratch, as uCos and Linux architectures I guess are > quite different ? > no idea about the diffrence between ucos and linux architecture. > Thanks in advance and looking forward to getting answers to my queries! -- H.
