[En-Nut-Discussion] Ethernet Reboot Issue

[Harald Kipp]

Tim,

Can you please try again with 4.1.99 or 4.2, which will be available
shortly. There had been several fixes.

Your assumption about stack problems might be correct. By default
the following sizes are set for the thread stacks:

dev.h:#define NUT_THREAD_NICRXSTACK 768
dhcp.h:#define NUT_THREAD_DHCPSTACK 768
os.h:#define NUT_THREAD_IDLESTACK 512
os.h:#define NUT_THREAD_MAINSTACK 768
sntp.h:#define NUT_THREAD_SNTPSTACK 768
tcp.h:#define NUT_THREAD_TCPSMSTACK 768

These may be increased, specifically NUT_THREAD_MAINSTACK,
NUT_THREAD_NICRXSTACK and NUT_THREAD_TCPSMSTACK.

Harald
