Hi Boxsport,
I'm also having the same issue of killed Orange5 clone v1.34. Can you share the bin file you have?
For how to use sam-ba, there is a youtube video FYI:
https://www.youtube.com/watch?v=HsLmJtrzsnE
Using the AT91SAM7S SAM-BA on-chip bootloader and the SAM-BA in-system programming software to load firmware to the AT91SAM7S256 microcontroller via the USB port. Read the tutorial at:
http://startingelectronics.org/tutori... No external programmer is needed, the firmware is loaded to the microcontroller's Flash memory from the USB port using the SAM-BA in-system programming software that is available for free from Atmel. The tutorial at the above link contains more information about the hardware and where to download the SAM-BA software from.
#3 post also looks interesting.
Hardware Requirements:
In order for the boot loader to work, there are some hardware requirements that must be met on the microcontroller circuit:
• The USB microcontroller pins must be connected to a USB connector.
• An 18.432 MHz crystal must be used for the microcontroller oscillator to enable a 40MHZ clock for USB operation.
• Pin PIOA16 (PA16) must be dedicated to switching on the USB pull-up resistor - usually through a transistor.
• The TST pin needs to be connected to a jumper to be able to pull it high.
• Pins PA0, PA1 and PA2 must all be pulled high when the TST pin is pulled high.
Thanks,
Ken
