Hi,

<snip1>

Forgot this one: Debian also tends to use some beta versions of the "make" tool which are obviously very broken. Make sure to use only stable versions.

Is it possible that there is any chace that you get an enetInt just after the first irq_install_handler? Can you put a printf at the beginning of the entInt?

First of all a big thank you to Matthias and Wolfgang for their answers!

I've put some printf statements into enetInt and associated functions and tested the code with CONFIG_NET_MULTI enabled and disabled. As Matthias suspected an enetInt is fired just after the first irq_install_handler. The console output of both configurations is inserted below.

For both configurations: - The 'mtdcr (uicer, mfdcr (uicer) | (0x80000000 >> i)' statement in irq_install_handler is the last instruction, before enetInt is entered. - As soon as enetInt returns, it re-enters.

But: - For CONFIG_NET_MULTI defined the problem occurs already while starting. In contrast I get the U-Boot prompt, if it is not defined. - For CONFIG_NET_MULTI defined, there is _NO_ printf output in enet_init, which seems very strange to me (see console output below).

Do the console output and my observations ring any bells? Do you have ideas where the problem could lie and what else I could try to solve it?

Thank you very much, Reto
