#REDIRECT [[CM-X300: U-Boot: Firmware Update]]
 
 
=== Preliminary ===
 
Some basic steps are needed to be taken in order to update the CM-X300 firmware successfully:
 
* Make sure to power off the CM-X300 board
 
* Connect one end of the supplied serial cable to your module's base board and the other one to your host system
 
* Start terminal console application on your host system and configure the following:
 
** Set the serial port to one with the attached cable
 
** Set baud rate to 38400 bps
 
** 8 bit per frame
 
** 1 stop bit
 
** no parity
 
** no flow control
 
* Turn the CM-X300 board on
 
* Now you should get the U-Boot command prompt in your terminal application
 
{{Note| If you have an operating system installed or U-Boot environment configured for auto boot, you will have to stop the auto boot sequence by pressing any key in your terminal application during the start of the boot process!}}
 
U-Boot firmware could be updated either from [[U-Boot_for_CM-X300#USB_flash_drive|USB flash drive]] (with FAT filesystem), or from [[U-Boot_for_CM-X300#Network_tftp_download|Network tftp download]].
 
Either method is done from U-Boot command line.
 
 
 
=== USB flash drive ===
 
{{Note| Please, connect your flash drive directly to the base board of the module! Do not use any USB hubs or other separating equipment!}}
 
To update the U-Boot firmware via USB flash drive, follow the instructions precisely!
 
* Start the U-Boot USB subsystem and check that your storage device is ready and contains the firmware
 
** Type: ''usb start''
 
** Type: ''fatls usb 0'' to ensure you have the firmware in place
 
<pre>
 
U-Boot> usb start
 
(Re)start USB...
 
USB:   scanning bus for devices... 2 USB Device(s) found
 
      scanning bus for storage devices... 1 Storage Device(s) found
 
U-Boot> fatls usb 0
 
  524288  cm-x300-firmware
 
 
 
1 file(s), 0 dir(s)
 
</pre>
 
 
 
* Load the firmware to memory
 
** Type: ''fatload usb 0 80a00000 <firmware filename>''
 
 
 
<pre>
 
U-Boot> fatload usb 0 80a00000 cm-x300-firmware

</pre>
 
* Proceed to [[U-Boot_for_CM-X300#Update_process|Update process]] section
 
 
 
=== Network tftp download ===
 
In order to use this update method, you need:
 
* TFTP service/server installed on your host system
 
* Firmware file should reside in the root directory of TFTP service
 
To update the U-Boot firmware via tftp download, follow the instructions precisely!
 
* Download the firmware to module's memory
 
** Type: ''tftp 80a00000 <firmware filename>''
 
<pre>
 
U-Boot> tftp 80a00000 cm-x300-firmware
 
dm9000 i/o: 0x8000010, id: 0x90000a46
 
DM9000: running in 16 bit mode
 
MAC: 00:01:c0:05:20:be
 
operating at 100M full duplex mode
 
TFTP from server 10.1.1.13; our IP address is 10.1.1.144
 
Filename 'cm-x300-firmware'.
 
Load address: 0x80a00000
 
Loading: ####################################
 
done
 
Bytes transferred = 524288 (80000 hex)
 
</pre>
 
* Proceed to [[U-Boot_for_CM-X300#Update_process|Update process]] section
 
{{Note| If you get the "''could not establish link''" message, check that your ethernet plugs are in place and try again.}}
 
 
 
=== Update process ===
 
{{Warning| DO NOT RESET OR POWER OFF THE MODULE DURING THE UPDATE PROCESS! DOING SO MAY RESULT IN DISABLED MODULE!}}
 
 
 
* Flash the firmware to onboard NAND storage
 
** Type: ''nand erase 0 80000''
 
** Type: ''nand write 80a00000 0 80000''
 
<pre>
 
U-Boot> nand erase 0 80000
 
 
 
NAND erase: device 0 offset 0x0, size 0x80000
 
Erasing at 0x60000 -- 100% complete.
 
OK
 
U-Boot> nand write 80a00000 0 80000
 
 
 
NAND write: device 0 offset 0x0, size 0x80000
 
524288 bytes written: OK
 
</pre>
 
* Now you may reset the board
 
 
 
{{Important|In case you use Windows CE and you update U-Boot, you will need to load the ImageUdater after the U-Boot update. There is no need to install the image again. This will update the NAND flash metadata that is crucial for Windows CE.}}
