[En-Nut-Discussion] Bootmon uses different network name than Nut/OS

[Ernst Stippl]

Hi!

The function "UserEntry(void)" in bootmon.c contains a call to "
BootConfigWrite()" (located in config.h).

Config.h contains the definition of confnet (which contains the "ETHERNUT"
name).
The macro EE_CONFNET is set at:

File NUT\BOOT\BOOTM102\MAKEDEFS:
DEFS += -DEE_CONFNET=64

This "64" corresponds to loc 0x40 in the RTC NVRAM where the information is
stored.

I experienced this while working on an Ethernut3 Rev-D board.

Did you peek into the NVram to see what was actually stored after you
applied the change from "ETHERNUT" to "eth0"?

Regards
Ernst

Nut/OS

Hello,

Which part of source should I modify to get Nut/OS working?
I tried to change string "ETHERNUT" to "eth0" in confnet structure in 
file config.c, but it didn't work. Neither worked changing 
DEV_ETHER_NAME to "ETHERNUT" in board.h ??? I have 4.4.1 version but I 
tried it with 4.1.9 and the same error :(
