Re: [ECOS] EB40LS ping_test problem

Yes, u are right!
The clocktruth is ok, but tm_basic is not.
I enable ASSERT, and got the message:
================================================================
Init device 'cs8900a_eth0'
ASSERT FAIL: <1>at91_misc.c[243]hal_interrupt_set_level() Invalid level
================================================================
I found the code in if_cs8900a.c:
cyg_drv_interrupt_create(cpd->interrupt,
                             0, // Priority - what goes here? <== ???
                             (cyg_addrword_t)cpd, //  Data item passed to
interrupt handler
                             (cyg_ISR_t *)cs8900a_isr,
                             (cyg_DSR_t *)cs8900a_dsr,
                             &cpd->interrupt_handle,
                             &cpd->interrupt_object);
    cyg_drv_interrupt_attach(cpd->interrupt_handle);
Is this a bug? hal_interrupt_set_level accept level between 1~7
after change the priority, run tm_basic:

I think it block at cyg_semaphore_wait(&synchro) in run_thread_switch_test
();
I am still tracing.

It should like something more fundamental is wrong. Maybe you clock is
not working. Try running the test program clocktruth and tm_basic. See
if they work correctly.
