i am using luminary micro's EV-LM3S811...while writting my code in keil software its build is ok ..but while trying to download from FLASH menu its showing the message bellow:
error: flash download failed.target dll has been cancelled... plz help....
Do you connect the board using the on-board debugger or with ULINK?
What other errors do you get?
well...Reinhard Keil i have figured out my problem by this time .i am explaining u. i was working with keil and EV-LM3S811.Board has been working for some time,but stoped,when I have done some programing for GPIO.I have tried to programme some pin that is on same port as JTAG,and mybe suddenly I have used this pins also.
Programme that I have downloaded last, works.But I can not programme board any more.
And now when I try to download the hex file the IDE gives me an error saying " Flash Download failed Target DLL has been cancelled ".
Are there any posibilities to erase flash my self. how do I recover the debugging functionality? The LM3S811 data sheet indicates that " This can be avoided with a software routine that restores JTAG functionality using an external trigger." However no more details are provided. i found several post in luminary micro's forum where all faced this problems but no solution given. my question is now whether it is possible to solve or this board becomes useless totally.
