U-Boot for the Congatec QMX6 boards
|
||||
|
||||
This file contains information for the port of U-Boot to the Congatec
|
||||
QMX6 boards.
|
||||
|
||||
1. Building U-Boot
|
||||
------------------
|
||||
|
||||
- Build U-Boot for Congatec QMX6 boards:
|
||||
|
||||
$ make mrproper
|
||||
$ make cgtqmx6eval_defconfig
|
||||
$ make
|
||||
|
||||
This will generate the following binaries:
|
||||
|
||||
- SPL
|
||||
- u-boot.img
|
||||
|
||||
2. Flashing U-Boot in the SPI NOR
|
||||
---------------------------------
|
||||
|
||||
Copy SPL and u-boot.img to the exported TFTP directory of the
|
||||
host PC (/tftpboot , for example).
|
||||
|
||||
=> sf probe
|
||||
|
||||
=> setenv serverip <server_ip_address>
|
||||
|
||||
=> setenv ipaddr <board_ip_address>
|
||||
|
||||
=> tftp 0x12000000 SPL
|
||||
|
||||
=> sf erase 0x0 0x10000
|
||||
|
||||
=> sf write 0x12000000 0x400 0x10000
|
||||
|
||||
=> tftp 0x12000000 u-boot.img
|
||||
|
||||
=> sf erase 0x10000 0x70000
|
||||
|
||||
=> sf write 0x12000000 0x10000 0x70000
|
||||
|
||||
Reboot the board and the new U-Boot should come up.
|
||||
|
||||
3. Booting from the SD card
|
||||
---------------------------
|
||||
|
||||
- Flash the SPL image into the SD card:
|
||||
|
||||
sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
|
||||
|
||||
- Flash the u-boot.img image into the SD card:
|
||||
|
||||
sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
|
||||
|
||||
- Insert the SD card into the big slot.
|
||||
|
||||
The boot medium of Congatec QMX6 boards is the SPI NOR flash, so boot
|
||||
the board from SPI first.
|
||||
|
||||
It is also possible to boot from the SD card slot by using the 'bmode'
|
||||
command:
|
||||
|
||||
=> bmode esdhc4
|
||||
|
||||
And then the U-Boot from the big slot will boot.
|
||||
|
||||
Note: If the "bmode" command is not available from your pre-installed U-Boot,
|
||||
these instruction will produce the same effect:
|
||||
|
||||
=> mw.l 0x20d8040 0x3850
|
||||
=> mw.l 0x020d8044 0x10000000
|
||||
=> reset
|
||||

U-Boot console UART selection:
|
||||
------------------------------
|
||||
|
||||
The U-Boot port for this congatec board currently supports two different
|
||||
configurations (defconfig files). The only difference is the UART that
|
||||
is used as the U-Boot console UART. The default defconfig file:
|
||||
|
||||
conga-qeval20-qa3-e3845_defconfig
|
||||
|
||||
provides this console on the UART0 which is provided via a Winbond
|
||||
Super-IO chip connected on the congatec Qseven 2.0 evaluation carrier
|
||||
board (conga-QEVAL). This UART is the one provided with a SubD9
|
||||
connector on the mainboard (the low one). The 2nd defconfig file:
|
||||
|
||||
conga-qeval20-qa3-e3845-internal-uart_defconfig
|
||||
|
||||
provides the U-Boot console on the BayTrail internal legacy UART,
|
||||
which is routed from the QSeven SoM to the X300 connector on the
|
||||
baseboard. Here is called COM2. The baseboard already provides the
|
||||
RS232 level shifters. So a TTL-USB UART adapter does not work in
|
||||
this case. The signals need to get connected directly to the
|
||||
RS232 level signals of the PC UART via some adapter cable.
