8.6 Bootloader Detailed Process
8.6.1 Detailed Description
When the L100 enters the Bootloader, the device is in the “Waiting State” with “Bootloader…” in Line 0
of the LCD display. In this state, the device can only receive the
Get Version
command. The expected
response is the Bootloader version.
The L100 can receive the Get Version command and all Data Blocks commands:
• If the L100 successfully receives Get Version command, it respond with “Bootloader” characters.
• If the L100 successfully receives a Data Block command, it verifies the block data format,
version, and signature.
•
If verification is OK, the L100 copies the block data into the Application Area and responds ACK .
•
If verification produces an error, the L100 responds NAK with an error code and waits for the
block data again. If one data block continuously fails three times, the L100 erases all applications
and responds
NAK
with an error code, then waits for the first data block in the Bootloader state.
If the Bootloader times out (30 seconds), and if the application is not modified, the L100 returns to the
old application; otherwise the L100 erases all applications and exist in the Bootloader state.
