Hi Charles Manning, I am working with yaffs on cygwin environment.. I am having two tasks at my hand.. 1. i have to verify the yaffs image created on cygwin environment will work as efficient as in other environment. 2. then i need to modify the yaffs code in such a way, mkyaffsimage should take input as a tar file rather than a directory. As a new-bie to yaffs, i need your views and some pointers on this area.. Thanking you, Ram ---------- Forwarded message ---------- From: Laurie van Someren Date: Wed, Dec 24, 2008 at 6:20 PM Subject: yaffs technical support To: roy basavaraju Ram, I am not really competent to answer your question to the YAFFS list, but Charles Manning's reply to a similar question recently is as follows:- -------- Forwarded Message -------- From: Charles Manning Cc: laurie@aleph1.co.uk Subject: re: yaffs technical support Date: Wed, 24 Dec 2008 13:48:10 +1300 Hello Further to my last email... I built and ran the test code in cvs under cygwin with no modifications. Process as follows: 1) You need cygwin with make, gcc etc. 2) Fetch tarball from http://www.aleph1.co.uk/cgi-bin/viewcvs.cgi/yaffs2/ 3) Unpack tarball 4) cd to yaffs2/direct 5) make 6) Run initialisation for test as follows: ./yaffs_test M18-1 fw_update_init 111 7) Run test code as follows: ./yaffs_test M18-1 fw_update 111 or by running the run_fw_update_test.sh script Regards Charles I hope this will help.
