Trouble with pic18f4620 application (solved)

MIOS programming (C)
1

Hi,

I’ve tried to upload my application to a 18f4620 core

All modifications as described on the wiki page were executed

When I upload my code with MIOS studio v7.4 all goes well (code from 0x3000->0x6EFF)

but after upload MIOS reboots and hangs while displaying:

Rebooting MIOS

the only way to get rid off this is to upload MIOS v1.9 again…

the previous version of my code works OK (code from 0x3000->0x6BFF)

this version was not modified for 18f4620

any clues?

I know you said you’d done all this stuff but just to check, did you modify the linker script?

Hi Stryd,

thanks for your time, here’s my linker script:

OK mystery solved, I did remove my bankstick module to test the IIC_midi module

and the core just hanged because of some bankstick code in Init()  ::slight_smile:

I disabled this code and everything worked fine…
