[ECOS] Problem about redboot

[ECOS] Problem about redboot

[ness]

Hi
    I am porting redboot for mips vrc4373. We just need ethernet debug, so
I did not write flash driver.
    When I invoke hal_if_init to initial the hal_virtual_vector_table, I
meet the problem.Two functions (hal_ctrlc_isr_init and hal_ctrlc_isr) are
multiple defined. In the directory common they are defined first, and in
the directory mips they are defined second. I do not know how to change
them.
    Who can tell me how to deal with it.
    Many thanks.

The vrc4373 doesn't implement the "standard" virtual vector support. What
you are seeing is an oversight that the hal_ctrl_isr* functions in
hal/common were not sufficiently conditionally compiled, which I will fix.
[ Jesper, I will make these functions conditional on
CYGSEM_HAL_VIRTUAL_VECTOR_SUPPORT ]

To implement redboot you would need to implement virtual vectors for the
vrc4373 platform. There are plenty of examples in other platforms.

But, but, but, that shouldn't be necessary... :)

        cdl_component CYGSEM_HAL_VIRTUAL_VECTOR_SUPPORT {
            display     "Enable use of virtual vector calling interface"
            active_if   CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT
            calculated  1
            description "
                Virtual vector support allows the HAL to let the ROM
                monitor handle certain operations. The virtual vector table
                defines a calling interface between applications running in
                RAM and the ROM monitor."
            compile     hal_if.c hal_misc.c
        }

The file is only ever compiled when there is virtual vector
support. The problem is the fact that the vrc4373 is not converted
properly/at all and the virtual vector support was still attempted
used.

Doh! I didn't see that. I'll revert my patch (even though it's harmless).

It's not converted at all. I take it "ness" must have somehow forced it on
in the configuration.

You'll have to get the latest sources - not 1.3.1! - either
from anonymous CVS or from a snapshot
(http://www.ecoscentric.com/snapshots)

Yes, in general RedBoot can do this.  What target platform 
are you using?

[ECOS] problem about redboot

[zhe zhang]

I want to use redboot to boot another OS . I downloaded ecos1.3.1 and some document , such as "user guide" and "redboot install"

But I can not find out how to get the booter , I used ecosconfig to config as "redboot install" tell me , but I found error "no this template". The command is "econfig new pc redboot ". It does not do .

Can u give me some advice ?

By the way , I want to use redboot to load my OS via network or serial port , did someone work it out ? Can it work well ?

thank u
