If the CPU is ARM does it have JTAG or SWD test access points.
We need a datasheet about the ARM11!

- The ARM11 IP (intellectual property) has JTAG support, however this port can probably be permanently disabled internally. So there is no way of knowing if this port even still works or exists in the first place.
- For dumping NAND, you need to hook up the NAND pins to an FPGA or microcontroller. Then you need to follow the eMMC hardware protocol to read out the data in the various sectors. --Neimod 07:06, 11 September 2011 (CEST)
