Bricked RDV4 - Wrong bootloader address?
Hi All,
It seems like i've bricked one of my Proxmarks RDV4.
My HW has only one Xilinx chip, it's missing the AT91.
I connected the JTAG header to a JLINK and everyting works smoothly, after I finished programming the bootloader to 0x00100000 I am getting an error on my USB device "Unknown USB Device (Device Descriptor Request Failed)".
I would like to know if the bootloader stayed at the address (0x00100000) after the HW moved to the single chip design?
To me it seems like I am writing the bootloader to the wrong address...

Did you follow the jtag instructions?

Since you have jtag possibilities you can revive your device.
