[U-Boot-Users] effort required to port u-boot
Hi,
Does anyone have an idea of the effort required to port the full uboot to a new arm based target?? Please excuse me for the nature of the question but if anyone has done it already he can suggest abt how much time he took to port the whole u-boot on a new target (just a very rough estimate), assuming that the developer has a very good knowledge of the target but at a comfort level [medium] on linux..
Any comments will be really helpful

It only took me about a week to port the Marvel (64360) based reference board. On the other hand it took me a month to get it up and running on 440gp based board (using the 405gp as a reference)... --- "Gupta, Kshitij" kshitij@ti.com wrote:

I ported u-boot to a new x86 board in a couple of days. I haven't booted Linux yet because I need to get a network adapter driver working.

Dear Kshitij,

Looking back at the last 10...20 ports the average effort is in the order of 8 to 12 days, depending on the complexity of the board, number and type of peripherals to support, and special features required. Of course this includes serious testing.
If you know the hardware really well, and there are no hardware related problems to solve, and you know U-Boot very well, and you have access to a BDI200, and you are fluent witn the BDI2000 and GDB, then you probably can do it faster.
But then please don't be surprised when your first port runs into problems after 3 weeks of work, and is still not running after two or three months. There is a lot of tinly little details which can cause serious headaches.
