Firmware update
The ATS7120/ATS7121 firmware is stored in a flash memory
on the board. The recommended way to update this firmware
is by placing an EPROM/flash into the upgrade socket on the
board, that will then be copied into the on-board flash memory.
The procedure is as follows:
1. Power down the ATS7120/ATS7121
2. Insert the upgrade EPROM/flash into the upgrade socket
(IC26)
3. Position the jumpers FLASH 4 Mb and EPROM 4 Mb
according the diagram that can be found in the Release
Notes document accompanying the firmware update.
4. Power up the ATS7120/ATS7121
The ATS7120/ATS7121 will detect the EPROM/flash, and
will start the update procedure. The process can be
followed by looking at the LEDs. The LEDs indicate the
following steps:
•
LED L1: Validity check.
•
LED L2: Flash erase.
•
LED L3: Flash program.
•
LED MI (Green): Flash Verify.
LED on indicates that the step was successful. A blinking
LED indicates that there was a problem during this step.
When the green MI LED goes on, the copy process has
completed.
5. Power down the ATS7120/ATS7121.
6. Remove the EPROM/FLASH from the upgrade socket
(IC26).
7. Power back on the ATS7120/ATS7121.
Note:
Always check the release notes of the firmware for the
required jumper settings for this specific firmware.
