Subject: [ECOS] Change redboot console on ep93xx
Date: Thu, 16 Jun 2005 03:55:00 -0000 [thread overview]
Message-ID: <20050616035500.i6JXkg5nVBouQ_2Gv_0wU4mTN6nt7dpKe4z3URmO5L4@z> (raw)
Hi,
I have a ep9312 board with 3 serial ports.The bootloader is redboot which default console is serial port 1#,
I want to change the console to serial port2# or port3#.
I have browsed the lists of "Redboot console on ep93xx",Manfraed have the same trouble.And I do as Gary say:
"You should not have to make these changes at all. Simply set
CYGPKG_REDBOOT_ANY_CONSOLE to 0/false
so RedBoot will only use a single console device. Then set
CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL to 1
for your desired channel."
In ecos.ecc I can't change the value of YGNUM_HAL_VIRTUAL_VECTOR_COMM_CHANNELS,
because "it calculated 1". so I have to change it in packages/hal/arm/arm9/ep93xx/v2_0/cdl/hal_arm_arm9_ep93xx.cdl
cdl_option CYGNUM_HAL_VIRTUAL_VECTOR_COMM_CHANNELS {
display "Number of communication channels on the board"
flavor data
calculated 1 //here ,I change this item to 3
}
And I have inactive CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL ,so I can set console comm_channel seperately.In
packages/redboot/v2_0/src/main.c-->cyg_start(),I change CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL) into
CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL);
rebuild and download it,but it's frustrated,there is nothing appear on all 3 serial ports.
can you help me!
Thanks !!
