CM-X300 Firmware Update process
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
|
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 from USB flash drive (with FAT filesystem), from MMC/SD Card (with FAT filesystem), or from Network tftp download. Either method is done from U-Boot command line.
USB flash drive
|
|
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
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)
- Load the firmware to memory
- Type: fatload usb 0 80a00000 <firmware filename>
U-Boot> fatload usb 0 80a00000 cm-x300-firmware reading cm-x300-firmware 524288 bytes read
- Proceed to Update process section
MMC/SD Card
To update the U-Boot firmware via MMC/SD Card, follow the instructions precisely!
- Start the U-Boot MMC subsystem and check that your storage device is ready and contains the firmware
- Type: mmc init
- Type: fatls mmc 1 to ensure you have the firmware in place
U-Boot> mmc init Detected: 1921024 blocks of 1024 bytes (1876MB) SD card. Vendor: Man 02 OEM TM "SA02G" Date 09/2009 Product: 2626238632 Revision: 0.4 mmc1 is available U-Boot> fatls mmc 1 524288 cm-x300-firmware 1 file(s), 0 dir(s)
- Load the firmware to memory
- Type: fatload mmc 1 80a00000 <firmware filename>
U-Boot> fatload mmc 1 80a00000 cm-x300-firmware reading cm-x300-firmware 524288 bytes read
- Proceed to 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>
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)
- Proceed to Update process section
|
|
If you get the "could not establish link" message, check that your ethernet plugs are in place and try again. |
Update process
|
DO NOT USE BATTERY, 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
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
- Check that your baudrate environment variable is set correctly - the same as your serial connection speed.
- Reset the board
|
In case of Windows CE usage, after U-Boot update, the ImageUdater will have to be loaded. There is no need to install the image again. This will update the NAND flash metadata that is crucial for Windows CE. |
