bill Posted February 10, 2007 Report Posted February 10, 2007 HelloToday i worked pretty much (let's say more than usually ;) on my little mb project, and i've been uploading some C code all day long on my pic18f452 (hundreds of uplodad and restarts), then, my core board (no din nor douts, just nude) stopped to work. Of course i tripple checked my code, but i even cant run a "hello world" program anymore. My lcd show the "MIOS V1.9" splash message, then turn blank.So i wonder if it's possible that i fried the pic by uploading too many times ?The strange thing, is that when i try to upload, MIOS restart (then go 'blank'), as it should, so it's the proof it's not completely freezed.What do you think ?

stryd_one Posted February 10, 2007 Report Posted February 10, 2007 (hundreds of uplodad and restarts)Oh good it's not just me. Man that bootloader is the bomb, imagine coding without it!Have you tried uploading MIOS again and then some skeleton app to test? Maybe somehow your app is killing MIOS. hmmmm Quote
/tilted/ Posted February 10, 2007 Report Posted February 10, 2007 (hundreds of uplodad and restarts)Is it possible that you have reached the PIC's "100,000 erase/write cycle Enhanced FLASH program memory typical" physical limit?I seriously doubt this, of course.It's not ye olde "RAM between 0x60-0x7f is not directly accessible" issue?

mess Posted February 10, 2007 Report Posted February 10, 2007 Strange, I did a LOT of uploads when working on projects and never had a failuremaybe your code got too big so that a part of mios was overwritten(this has happened to me a few times before I used the 18f4620)in that you can upload MIOS as Stryd suggestedIt's not ye olde "RAM between 0x60-0x7f is not directly accessible" issue?this is only an issue for the can enabled pics ...

Maybe somehow your app is killing MIOS. hmmmmYep, i have uploaded a "hello world" program that give the same results :(I'm giving up, and use a new pic ;) Quote
chuck Posted February 11, 2007 Report Posted February 11, 2007 Did you try uploading mios again? Quote
bill Posted February 12, 2007 Author Report Posted February 12, 2007 Did you try uploading mios again?Sure, i did :'( Quote
stryd_one Posted February 12, 2007 Report Posted February 12, 2007 Maybe thi PIC ID has become corrupted and it's sending the midi and lcd elsewhere... Reburn? Quote
