- Subject: [ECOS] How to Enable USB Slave
I want to enable USB in Redboot. Which is similar to ecos. So writing this email.
I have read http://ecos.sourceware.org/docs-latest/ref/usbs-intro.html
Here it is mentioned that "Easiest way to do this is to enable the configuration option CYGGLO_IO_USB_SLAVE_APPLICATION,
and the USB device driver and related packages will adjust accordingly"
But I don't know where to modify this.?
I have tried modifying ?build/ecos/packages/hal/arm/arm9/edb93xx/current/misc/redboot_ROMRAM.ecm
Add
package -hardware CYGPKG_DEVS_USB_D12 current? ;
??????????? package CYGPKG_IO_USB current? ;
??????????? package CYGPKG_IO_USB_SLAVE current? ;
??????????? package CYGPKG_IO_USB_SLAVE_ETH current? ;
but this is giving me errors :
*************
C CYGPKG_DEVS_USB_D12, "requires" constraint not satisfied: CYGIMP_DEVS_USB_D12_HW_ACCESS_HEADER
Unable to generate build tree, this configuration still contains conflicts.
Either resolve the conflicts or use --ignore-errors
make[1]: Entering directory `/newhome/vivek/linux-crater_1-0-3Redboot/build/ecos/build'
********************
I have checked CYGIMP_DEVS_USB_D12_HW_ACCESS_HEADER in ecos.ecc,
there is cdl_options for this, but did not understand why compilation is giving error (basically in ecosconfig tree) ?
do i have to check some header file implementing D12 registers ?
What should I do to resolve this. Any pointers...will help a lot.
Thanks in advance.
