Hi I need a encrypted bootloader for pic32mx795f512h, it must use a pendrive (support for FAT32). I write a file in the pendrive, when the pic powers-up and a key is pressed, the firmware verifies if a file is present in pic if yes, the firmware in pic is updated.

Hi, I can provide such system in less than 9 days. When a push button is pressed (connected to one of the pix32 pins), the pic32 will check if a file is present on usb stick; If yes, it loads it in firmawaere zone. Of course, code will be encrypted (decryption of bootloader will necessite a sequence of keys) Contact me back if interested. Cheers

I assume you want the PIC32 to be the USB host and when a USB pen drive is inserted the PIC checks for a specified file, checks if the file is usable and correct and auto-updates it's firmware. If this is the case I can do the job for you.

I have quit a good experience with PIC and PIC boot loaders so I can help you on this project. Got experience with PIC16 and PIC32 families. The following must be done if I understand the proposal correctly: 1. A file containing the PIC firmware is placed on an USB Stick 2. When the PIC device starts and a special button is pressed then the firmware is downloaded from the USB stick to the PIC and the PIC is programmed. Question: must the file really be encrypted or do you just want to make sure the the file on the stick is not corrupted ?
