Can't Program NOR Flash
If you have removed Supervivi from NOR and unsuccessfully tried to place u-boot in there I believe all you can do now is use JTAG to get Supervivi back into NOR. See the downloads page for H-JTAG. Why did you want to put u-boot into NOR?
thanks for reply i tried to get Supervivi back to NOR , but i get that error , now i can't do anything with NOR flash , i'm using H-JTAG and i read all about H-JTAG software . i just want to be sure i can download supervivi into NOR flash , i create a back up from NOR , and I downloaded uboot to make sure that Supervivi is gone , now i can't even erase nor flash . i only get that error :( i read all topic about nor but i did not fount anything usefull . thanks for your help sorry for poor english
*** i just want to be sure i can download supervivi into NOR flash , i create a back up from NOR , and I downloaded uboot to make sure that Supervivi is gone , now i can't even erase nor flash . i only get that error :( *** You have followed the process in "JTAGingTheNOR.pdf"? The first thing you have to do is get Supervivi back into NOR. I do not understand what you mean by "i create a back up from NOR". You don't need to backup NOR. I asked why you want to put u-boot into NOR, but you didn't answer. I have been playing with this board for over a year and I have never heard of anyone wanting to put u-boot into NOR. The normal process is Supervivi into NOR and then u-boot into NAND FLASH, then the kernel then the rootfs into NAND. Or kernel and roofs in a SD card or NFS. So, back to your main problem . . . you selected the correct Flash device as per the picture on the bottom of page 2, "probably the SST39VF1601"? Any of these help: http://www.friendlyarm.net/forum/search?cx=partner-pub-7044974384698216%...
thank you for your answer first i read the entire nor flash , whole 2 mb and save it as binary file , just for sure "You have followed the process in "JTAGingTheNOR.pdf"? The first thing you have to do is get Supervivi back into NOR." -- yes i followed the process first time and it worked until i put uboot in nor flash by mistake . and now the process is not working .now i cant access to nor flash so i cant do the normal process . when i want to program the flash Can't download driver to specified address error appears . "The normal process is Supervivi into NOR and then u-boot into NAND FLASH, then the kernel then the rootfs into NAND. Or kernel and roofs in a SD card or NFS." i know all this stuff and i did it before and worked fine . now i just want to put supervivi into nor flash to everything goes back to normal . my flash device is not SST39VF1601 , its something else , i cant remember the exact part number and i cant tell the exact number till tomorrow . in the link that you said somewhere said i should try init script , what's the init script ? how can i use it ? what script should i use ? thanks for your help
elenor, I think I understand your situation and sorry but I never made this mistake so I have no experience trying to "reclaim" the NOR. http://www.friendlyarm.net/forum/topic/1667 I don't know what Spacewalker is talking about. Sure is helpful when people find a solution to a problem that they then post back with the solution! Does a search on Google with the exact error message not turn up anything useful? If not, I would suggest re-posting your problem here and on http://groups.google.com/group/mini2440 with a title like "Can't access NOR with H-JTAG" Good luck. Dave
my problem solved . my NOR flash device is S29AL016D-M02 , and i used the init script that i attach to this post and it works well , now i can program my NOR flash with supervivi . thanks a lot dave
You are welcome. Good job attaching the fix. Where did you find this .rar file? I searched this forum and didn't find it. Dave
I found it on the dvd in my mini 2440 pack and i change it a little bit to work with my flash device. its HFC file but i couldn't attach it so i made it as a archive file . i'm SO HAPPY :D
Hey, i got the same problem like you, but my NOR FLash chip is AM29LV160DB can you edit your init script to my type of chip? Regards, Nanda -Indonesia
Hey elenor, i got the same problem like you, where to put your attachment and how to run it? Regards, yayan -Indonesia
