The sam7s and sam7x ports seems the closest to what I need (but still with = quite a few differences). With starting this port I would like some guidance in the format that the p= ort must be according to =93your=94 standards with regards to directory str= ucture and which layers to implement. The current structure is as follows w= ith my recommendations next to them:=20 ARM arch layer - great keep as is AT91 var layer =96 this layer contains a lot of platform specific info spec= ifically for AT91SAM7 series (for instance in var_io.h ) =96 why here, can= =92t it be moved to the platform specific source (plf_io.h)? Or shall I rat= her say how must I approach this to get the anonymous sources changed? I think = it will make things more structured and when I want to port the AT91SAM7A2 = series I only need to do platform changes and not variant changes as well. AT91SAM7S - How do you want the directory structure and why call the dire= ctory at91sam7s (and not at91sam7) when the x series is implemented in it a= s well and the variant name it resides under is at91sam7 (CYGPKG_HAL_ARM_AT91SAM7). Now must the new port be made alongside the at91= sam7s platform or completely independent from the existing port? How must t= his be done so that they will add the new port to the anonymous cvs format = wise etc? Can anyone give me some guidance on how to attempt this specific port?=20 Regards Hendrik Meiring MScEng student at the University of Stellenbosch South Africa
