Greetings.
I want to experiment with ATSAM3S4B chip from Atmel.
According to the documentation, it can be programmed by it's own USB with internal bootloader.
I wired one up as per datasheet, got the USB working, found the drivers and got Sam-ba 2.12 program that is supposed to do the magic.
Sam-ba detects the chip, and can read and write SRAM, but any attempt to write to flash result in OK report, and no changes in the flash.
No error messages, no clues, no googleable alternatives.
So, the question is - how do you write the flash in this chip over USB properly?
