[En-Nut-Discussion] nutconfigure and MCU-type

[Ernst Stippl]

Resent due to msg size on 1st try.. Sorry!

Hello!

After a long period of Ethernut "Quiteness" I tried to resurrect my Ethernut
2 today and started to compile the new (4.8 , 4.9) Nut/OS versions. 
I came across a strange error: When using Nutconfigure, I receive an error
"unknown MCU `Enhanced' specified" when compiling for  the Ethernut 2.1
board starting with Nut/OS version 4.8.4


The script output looks like:


D:\DRV-NUT\ethernut_4.8.4>path=D:\DRV-NUT\ethernut_\nut\tools\win32;D:\DRV-N
UT\winavr_4.2.2\bin;D:\DRV-NUT\winavr_4.2.2\utils\bin;C:\windows\system32;C:

-------------------
When using nutconf, the output looks OK (after I set the CPU type and save
the .conf file)

Notes:

Problems with regedit cause the "Cannot exec cc1"

nsf .. no such file 
Enhanced .. error in mcu type

 
I could not find what did change between 4.8.2 and 4.8.4 which could cause
this error. Any ideas?

 

regards
