Hi all,
I had a project which I could successfully programto my NXP uC using a J-link. When I upgraded my Keil version I could not upload it anymore (erase failed error). I tried downgrading Keil version to 5.12 (which worked previously) and I keep getting the error.
I'm able to program the same project using other computer so the problem should be in some config file. I tried uninstalling it and installing it again deleting all files left in AppData and keil_v5 folders and also the what I could find in Windows key registry and still didn't get it working.
Is there something else I need to remove to completely uninstall it?
Regards,
Mikel
Hi Hans,
I'm getting an erase fail error. I'm programming an LPC1820 with a J-Link through SWD. I also deleted the J-Link drivers, but I may not did it right because when I plug the J-Link again Windows automatically install it again. I'm using Windows 7.
Thanks in advance.
Miguel
Hi Miguel,
Did you write this forum entry as well? http://www.keil.com/forum/61267/
If yes, check if th LPC1820 can be programmed at all. This device does not have an on-chip Flash.
Yes, I'm the same. I decided to open a new because I got to program it on another computer with the same project settings. So I suspect is something wrong in Keil installation and I cannot solve it uninstalling and installing it again.
LPC1820 does not have internal flash, but I'm using external flash connected through SPIFI. I could succesfully program the same uC before with my computer and that's what makes me mad.
Hi Miguel, that's hard to say. When you reinstall an older version of uVision, all MDK files get replaced. A newer J-Link driver might have updated the firmware of J-Link. As far as I know, you have another PC which can still program the LPC1820. You can try the same J-Link to see if the firmware makes a difference. Are you using a 'Init File' for flash programming (Options for Target - Utilities - Init File) if if yes, is it the same one?
I've already solved the problem. The corrupted file was the algo file located in Keil_v5/ARM/Flash/LPC18xx43xx_S25FL032.FLM. Many thanks for your help and your time.
Hi Miguel, I have a similar problem. What did you do with that file?
