Flashing the NAND using SAM-BA
|
||
|
|
==============================
|
||
|
|
|
||
|
|
This document explains how to flash a basic Buildroot system on various
|
||
|
|
Atmel boards. Additional details can
|
||
|
|
also be found on the Linux4SAM website, in particular here:
|
||
|
|
http://www.at91.com/linux4sam/bin/view/Linux4SAM/GettingStarted
|
||
|
|
|
||
|
|
This guide covers the following configurations:
|
||
|
|
- at91sam9g45m10ek_defconfig
|
||
|
|
- at91sam9rlek_defconfig
|
||
|
|
- at91sam9x5ek_defconfig (at91sam9g15, at91sam9g25, at91sam9x25,
|
||
|
|
at91sam9g35 and at91sam9x35)
|
||
|
|
- atmel_sama5d3xek_defconfig (sama5d31, sama5d33, sama5d34, sama5d35,
|
||
|
|
sama5d36)
|
||
|
|
- atmel_sama5d3_xplained_defconfig
|
||
|
|
- atmel_sama5d4ek_defconfig
|
||
|
|
- atmel_sama5d4_xplained_defconfig
|
||
|
|
|
||
|
|
These configurations will use AT91Bootstrap, u-boot and a linux kernel from
|
||
|
|
the git trees maintained by Atmel. They also build u-boot SPL when
|
||
|
|
available, it can replace AT91Bootstrap.

Configuring and building Buildroot
|
||
|
|
----------------------------------
|
||
|
|
|
||
|
|
make <board>_defconfig
|
||
|
|
make
|
||
|
|
|

|
||
|
|
Flashing the board
|
||
|
|
------------------
|
||
|
|
|
||
|
|
Connect the board:
|
||
|
|
o at91sam9g45m10ek: DBGU: J10, USB sam-ba: J14
|
||
|
|
o at91sam9rlek: DBGU: J19, USB sam-ba: J21
|
||
|
|
o at91sam9x5ek: DBGU: J11, USB sam-ba: J20
|
||
|
|
o sama5d3xek: DBGU: J14, USB sam-ba: J20
|
||
|
|
o sama5d3 Xplained: DBGU: J23, USB sam-ba: J6
|
||
|
|
o sama5d4ek: DBGU: J22 or J24, USB sam-ba: J1
|
||
|
|
o sama5d4 Xplained: DBGU: J1, USB sam-ba: J11
|
||
|
|
|
||
|
|
Start the board in RomBOOT:
|
||
|
|
o at91sam9g45m10ek:
|
||
|
|
1. open JP8, JP10 and JP12
|
||
|
|
2. start the board
|
||
|
|
3. close JP8, JP10 and JP12
|
||
|
|
|
||
|
|
o at91sam9rlek:
|
||
|
|
1. J11 on 1-2 (BMS=1), open J12 and J13
|
||
|
|
2. start the board
|
||
|
|
3. close J12 and J13
|
||
|
|
|
||
|
|
o at91sam9x5ek:
|
||
|
|
1. open JP9 and:
|
||
|
|
- Cogent: open *NCS jumper
|
||
|
|
- Embest: open SW1
|
||
|
|
- Ronetix: open J1 and J2
|
||
|
|
2. start the board
|
||
|
|
3. close JP9 and:
|
||
|
|
- Cogent: close *NCS jumper
|
||
|
|
- Embest: close SW1 (ON position)
|
||
|
|
- Ronetix: close J1 and J2
|
||
|
|
|
||
|
|
o sama5d3xek:
|
||
|
|
1. start the board
|
||
|
|
2. push BP4 and BP1
|
||
|
|
3. release BP1
|
||
|
|
4. release BP4
|
||
|
|
|
||
|
|
o sama5d3 Xplained:
|
||
|
|
1. open JP5 (NANDCS) and JP6 (SPICS)
|
||
|
|
2. start the board
|
||
|
|
3. close JP5 ans JP6
|
||
|
|
|
||
|
|
o sama5d4ek:
|
||
|
|
1. start the board
|
||
|
|
2. push BP3 and BP4
|
||
|
|
3. release BP4
|
||
|
|
4. release BP3
|
||
|
|
|
||
|
|
o sama5d4 Xplained:
|
||
|
|
1. close JP7 (BOOT_DIS)
|
||
|
|
2. start the board
|
||
|
|
3. open JP7
|
||
|
|
|
||
|
|
"RomBOOT" should appear on your console (this should be ttyUSBx or ttyACMx)
|
||
|
|
|
||
|
|
Now locate the USB sam-ba interface it should be ttyACMx, usually ttyACM0
|
||
|
|
dmesg on your machine should give:
|
||
|
|
usb 1-2.1.4: New USB device found, idVendor=03eb, idProduct=6124
|
||
|
|
usb 1-2.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
|
||
|
|
cdc_acm 1-2.1.4:1.0: ttyACM0: USB ACM device
|
||
|
|
|
||
|
|
Look for idVendor=03eb, idProduct=6124, this is the interface you want to use.
|
||
|
|
|
||
|
|
You can then flash the board using the provided flasher.sh script in board/atmel:
|
||
|
|
|
||
|
|
board/atmel/flasher.sh <builddir_path> <interface> <board>
|
||
|
|
|
||
|
|
For example, for an out of tree build made in
|
||
|
|
/tmp/atmel_sama5d3_xplained/ for the sama5d3 Xplained, you would use:
|
||
|
|
board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained
|
||
|
|
|
||
|
|
Reboot, the system should boot up to the buildroot login invite.
