CM-A510 Firmware Update process
Preliminary
Some basic steps are needed to be taken in order to update the CM-A510 firmware successfully:
- Make sure to power off the CM-A510 board
- Connect the host PC to the CM-A510 via the serial cable supplied with the CM-A510 evaluation kit.
- Start terminal console application on your host system and configure the following:
- Set the serial port to the COM port to which the serial cable is connected.
- Set baud rate to 115200 bps
- 8 bit per frame
- 1 stop bit
- no parity
- no flow control
- Turn on the CM-A510 system
- The U-Boot boot-loader will start and you will get a command prompt
|
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 can be updated from a Network TFTP download, from a USB flash drive (with FAT filesystem), or from a Hard disk (with FAT/EXT2 filesystem). Either method is done from U-Boot command line.
Preferred U-Boot Update Option
|
DO NOT RESET OR POWER OFF THE MODULE DURING THE UPDATE PROCESS! DOING SO MAY RESULT IN DISABLED MODULE! |
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!
- You can use U-boot dhcp command to obtain IP address or manually set ipaddr environment variable:
> setenv ipaddr <CM-A510 ip address>
- Set serverip environment variable and save the new environment to SPI flash:
> setenv serverip <host ip address> > saveenv
- Download the firmware using the bubt command.
- Type: bubt <firmware filename>
- Type: y to override U-Boot environment with default one

Other U-Boot Update Options
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
CM-A510>> usb start
(Re)start USB...

- Proceed to Update process section
Hard Disk
To update the U-Boot firmware via Hard Disk, follow the instructions precisely!
- Start the U-Boot SATA subsystem and check that your storage device is ready and contains the firmware
- Type: ide reset
- Type: fatls/ext2ls ide 0:1 to ensure you have the firmware in place
CM-A510>> ide reset
