RE: [ECOS] enabling flash from configtool

[Matt Sartori]

I've worked it out. I didn't realise (until I started looking through
the "Embedded software development with eCos" book) that I need to
import the redboot_ROM.ecm file as a separate step when using
configtool. 
Thanks for your responses anyway. I hope this info proves useful to
someone else in the future.

You should be able to look in the .ecc file to see why your FLASH driver
is not being enabled.

[ECOS] error while linking : flash problem

[Indra Antonius Simalango]

Dear all,

I've built my eCos for pc_rltk8139 target with all package. While linking 
my application, I've some error messages like this :
---------------------------------------------------------------------------------

----------------------------------------------------------------------------------

If I don't want to use any flash component, which part of my file ecos.ecc 
should I modify?

Please share your experiences. 

Thank you.

Re: [ECOS] error while linking : flash problem

[Indra Antonius Simalango]

Thanks for your response,

I've done this :
#ecosconfig new pc_rltk8139 all
#ecosconfig remove flash
C_CYGPKG_JFFS2, "requires" constraint not satisfied: CYGPKG_IO_FLASH
C_CYGPKG_JFFS2, "requires" constraint not satisfied: 
CYGPKG_IO_FLASH_BLOCK_DEVICE

Is this allright?

Thank you.

No, you also need to remove the jffs2 packet since it depends on
having a flash driver, which you don't have.
