[ECOS] Problem for eCos adding packages

[ECOS] Problem for eCos adding packages

[-- Attachment #1.1: Type: text/plain, Size: 456 bytes --]

Hi!
    I  implement eCos2.11 on redhat Linux 8.0  and try to create RedBoot.
When I need to add serial driver, enter build->packages
then choose package item from "Availabe Packages" to
"Use these Packages"...press "add".
    My screen display Message "Add and remove hardware packages by selecting a new hardware template".

eCos cannot allow me to add this item......


Thanks for help.

What package were you trying to add?

I know where Gary's going with this, but may as well be explicit IMHO :-). 
You can't add a serial driver package as a serial driver is hardware 
specific.... and as a result it must be listed separately in the 
definition of the target in the ecos.db file. If there isn't a serial 
driver listed in the ecos.db target, that is probably because the driver 
doesn't exist/work for that target!

Besides, you don't want to add a serial driver package to redboot.... 
RedBoot uses polled I/O with interrupts off, and that comes from the HAL, 
not from the separate serial drivers which are aimed at eCos.
