Supported SD Card Devices

SAM9X35
SD Card Boot
SPI Flash Boot
The Galois field tables are mapped in the ROM just after the ROM code, as described in
11-9
Figure 11-9. Galois Field Table Mapping
For a full description and an example of how to use the PMECC detection and correction fea-
ture, refer to the software package dedicated to this device on Atmel’s web site.
The SD Card bootloader uses MCI0. It looks for a “boot.bin” file in the root directory of a
FAT12/16/32 formatted SD Card.
SD Card Boot supports all SD Card memories compliant with SD Memory Card Specification
V2.0. This includes SDHC cards.
Two kinds of SPI Flash are supported: SPI Serial Flash and SPI DataFlash.
The SPI Flash bootloader tries to boot on SPI0 Chip Select 0, first looking for SPI Serial Flash,
and then for SPI DataFlash.
It uses only one valid code detection: analysis of ARM exception vectors.
The SPI Flash read is done by means of a Continuous Read command from address 0x0. This
command is 0xE8 for DataFlash and 0x0B for Serial Flash devices.
