Firmware Updates
Method 2
Placing “.s19” file in “Update” folder and loading firmware manually and automatically.
For this test, user should create a folder “/Update/Vxxyyzzz” folder in microSD card and then place the “.s19” files
inside respective folders.
For example - “update/Vxxyyzzz/ xlee.s19” (Where, V is for version and xxyyzzz is the version number, Vxxyyzzz =
V1549206)
NOTES:
a. If Firmware version on the device and firmware version inside Update folders are same then nothing should
happen.
b. If multiple firmware version folders are available in the update directory then the version that is greatest /
latest should get updated to device.
Manual Firmware Update via %SR’s
With proper folder structure placed in microSD card, insert the card to device.
Set %SR154.10 high. If firmware version folder inside update directory is greater than the firmware version on the
device, then %SR154.16 will go high indicating firmware update process have started. Once firmware update pro-
cess will be completed, %SR154.10 and %SR154.16 bits goes low.
NOTE: There will be no busy symbol indication for this method. User should monitor %SR’s for the updates.
Set %SR154.12 bit to high if user program and register data should be cleared after the update.
Set %SR154.12 bit to low if user program should be present, register values should be retained and status of the
device needs to be retained after the update.
Auto firmware update via %SR’s
Setting %SR154.10 and %SR154.11 high, whenever new firmware folder is placed in the microSD card, firmware
update will happen automatically setting %SR154.16 bit high. Once firmware update process will be completed,
%SR154.16 bit will be reset but %SR154.10 and %SR154.11 will remain high (for auto update of firmware).
NOTE: There will be no busy symbol indication for this method. User should monitor %SR’s for the updates.
Set %SR154.12 bit to high if user program and register data should be cleared after the update.
Set %SR154.12 bit to low if user program should be present, register values should be retained and status of the
device needs to be retained after the update.
In all the methods, device will reset automatically after firmware update process is completed.
