23 Release Notes
23.1 Known problems
Flow control
—RTS may fail to de-assert quickly enough for some high-speed CPUs to stop sending data bytes correctly. For
high-speed transfers at baud rates greater than 460,800, Roving Networks recommends limiting the RX data to the maximum
Ethernet frame (1,460 bytes) and using a protocol to acknowledge that the remote host receives the data.
The UART does not support odd or even parity; only no parity is supported.
23.2 Current Firmware features and fixes
As of version 4.41 11/25/2013
Firmware update over UART using XMODEM 1K protocol.
Added new optional parameters in FTP update and XMODEM:
o
ftp
<option> <filename>
o
xmodem
<option>
<filename>
, where
<option>
is
r = download the firmware only. Do not set as boot image (if firmware integrity checks pass).
u = download the firmware and set as booth image (if firmware integrity check pass).
c = clean the file system before performing firmware update over FTP or XMODEM 1K protocol. This will delete
all the files on the Flash file system (including user defined configuration files) except the current boot image and
the factory default boot image.
