SECTION 5

1. SAM-BA

This part describes how to update the QIL-A9260 with the SAM-BA utility.

1.1. Introduction

Here is the default configuration of the nand flash memory:

Offset File Size Remark

0x00000000 nandflash_qil-a9260.bin =< 4Kb

0x00020000 u-boot.bin =<196Kb

0x000A0000 uImage_cpio ~3Mb Rescue linux kernel bound with a cpio RFS

0x00400000 uImage_jffs2 ~1.2Mb Linux kernel (mount the RFS from /dev/mtd1)

0x01000000 «Root FS» 120Mb The default root filesystem is located here.

0x08800000 «FS» 120Mb

When you want to update the QIL-A9260 module, you need to erase the first block of the

nandflash. Indeed if you want to be able to upgrade the QIL-A9260 with SAM-BA, the ROM boot

program don't have to find a valid ARM vector sequence (see the paragraph 13. AT91SAM9260

Boot program in the AT91SAM9260 datasheet). In order to erase the first block of the nand flash

memory, you should hold the SW1 user push button while resetting the board.

Now, let's see how to upgrade the QIL-A9260.

Datasheet GSG-00006-A01 15/34

If you put your own first level bootloader, don't forget to put a recovery function in order to be

able to erase the first block of the nandflash memory. Otherwise in order to use SAM-BA, you

should open JP2, start SAM-BA and then re-solder JP2. Only after this step, you could

upgrade the QIL-A9260 module.
