Re: Virtex-4 FX12 Mini-Module support

[Ales Gorkic]

Hi Aidan,

 

After I searched the web I found out that you have sucesfully run the
uClinux 2.4 on Virtex-4 MiniModule. I have developed a GSRD2 design on which
I would like to run uClinux. There are two problems:

I am new to linux

I don't know where to start

I would appreciate if you could share your design with me and give me help
with running it on my design.

 

Cheers,

Re: [PATCH] mpc52xx: Correct calculation of FEC RX errors.

[Sylvain Munaut]

Nice catch,
I knew something was wrong ( 4 billion errors ;) but I never bothered to
look
it up.

 'ifconfig eth0' command for mpc5200B-based cards shows error for RX.
 However none of RX MIB counters is set to value greater than zero.
 Number of errors is equal to number of multicast packet. In linux 2.4
 calculation of RX errors is slightly different and takes into account
 number of multicast packet. This change is a port of calculation method
 of RX errors for FEC controller from linux 2.4 to 2.6.
