Hi ALL,
Problem Summary: - I am facing a problem with the redboot build
environment while porting it to our ARM9 based SOC. I found that it's
not compiling the serial driver even though "ecosconfig check" shows
that the required package is present.
Detailed Description:- We make ARM9 based SOC and the UART IP block is
completely different. So, I need to develop a different low level UART
driver for our chip. I did the following:-
1) Created a folder called myUART in
\ecos-2.0\packages\devs\serial\arm and added necessary cdl and src files
in
the said directory.
2) Created a package called CYGPKG_IO_SERIAL_ARM_MYUART in
ecos.db which points to the CDL file in \ecos-2.0
\packages\devs\serial\arm\ myUART\ v2_0\cdl
3) Added following Lines in ecos.db
target my125Target {
alias { "myTarget" myTarget_arm9 }
packages { CYGPKG_HAL_ARM
CYGPKG_HAL_ARM_ARM9
CYGPKG_HAL_ARM_ARM9_MYTARGET
CYGPKG_ERROR
CYGPKG_IO
CYGPKG_IO_SERIAL
CYGPKG_IO_SERIAL_ARM_ MYUART
CYGPKG_DEVS_FLASH_INTEL_28FXXX
CYGPKG_DEVS_FLASH_ARM_MYTARGET
}
description "
The target provides the packages needed to run
eCos on our SOC based board."
}
After adding above mentioned lines, my expectation is myUART.c
located in \ecos-2.0\packages\devs\serial\arm\ myUART
\ v2_0\src\ would be compiled. But in reality I found that this is
not getting compiled.
Any help regarding this would be highly appreciated.
Best regards,
Sujoy Ray.

Hi Andrew,
As usual - you gave the correct starting point.
Thanks for your help.
Best regards,

Redboot uses the HAL serial driver, not the fully, interrupt serial
driver. The HAL serial driver should be in your
CYGPKH_HAL_ARM9_MYTARGET, normally in the file hal_diag.c
