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.
