Hello, I build the MidiBOX64 LowCost in the last month. Today was the day, I'ld start the box. So I'd first installed the MidiOX an get the Signal from the PIC every two seconds. All seemed to be ok. The Pix is an 18F452 which I'd buyed @ Mikes Shop. I'd downloaded the "mios_v1_9_pic18f452.hex" and tried to update the Pic. The first seconds all seems to be ok, the I'd received an error-message (Text like: Write protect in memory). I tried to install an other Version of the update ("update_with_old_mios.hex") to rescue my system (hadn't got a burner). Now the Pic doesn't react. When I start the Update, the MiosSudio shows, that the first Block is sended, and then nothings happens. Has someone of you an idea, how to save my Pic? The Sysex-Message isn't there anymore. (is it normaly when a System is insalled oder should there come an hint via Midi every few seconds two?) Freetings from Germany / Hannovre sends Andreas PS: Is there a chance to set the Pic back and install the Mios again?
