We're having some problems with a customer... we have over a hundred of
our lwIP 1.4.1 devices out in the field.
Our hardware is the Atmel ATSAME416E with the KSZ8081MNX PHY chip...
same config as the ATSAM4E_EK eval kit.
Project based on the THIRDPARTY_LWIP_RAW_BASIC_HTTP example.. I've added
FTPD, HSMCI, and SNTP to the mix. The box is an FTP site for an SD card
attached to industrial equipment.
Our customer is experiencing lockup of the processor... the lockup
symptom is the status LED stays BLUE. At this condition we're supposed
to quit kicking the watchdog, resulting in a reset... obviously this is
not happening, not sure why.
The unusual thing about this customer's installation is that they have a
huge subnet... the mask is FF.FF.F0.00... 4094 hosts. This appears to
me to be way too much, but our other pieces on this network (Lantronix
Spider-based) appear to be able to take this load. I'm assuming there's
a lot of horsepower in the Spider, it gets pretty hot in operation,
where our board runs cool.
Should lwIP be able to handle this, given my current hardware? I
realize this is more a hardware question than a lwIP question, but
perhaps someone can help me. Thanks for your time.
