frying the pic ?

[bill]

Hello

Today 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 ?

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

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?

Strange, I did a LOT of uploads when working on projects and never had a failure

maybe 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 suggested

this is only an issue for the can enabled pics ...

Yep, i have uploaded a "hello world" program that give the same results :(

I'm giving up, and use a new pic ;)

Did you try uploading mios again?

Sure, i did  :'(

Maybe thi PIC ID has become corrupted and it's sending the midi and lcd elsewhere... Reburn?

;D congratulations for your Gameboy place on BOTB..

mhh.. try to upload application or mios1.9 within 2 seconds after switch power on.

I'd similar problem.. after that all runs fine.
