Problems while configuring usb gadget mode with DM355EVM

Pavel Goryunov

Hello, everyone. I have a task to realize the read/write access from linux/pc host to the NAND memory of DM355EVM over usb.

I deployed default uImage from DVSDK 3.10 and target filesystem over NFS.

I've tried to build my own kernel with the support of usb storage device using 2.6.32 kernel sources. But compiling process was interrupted with those errors:

CC drivers/usb/gadget/r8a66597-udc.o
drivers/usb/gadget/r8a66597-udc.c: In function 'r8a66597_probe':
drivers/usb/gadget/r8a66597-udc.c:1585: error: implicit declaration of function 'IS_ERR'
drivers/usb/gadget/r8a66597-udc.c:1588: error: implicit declaration of function 'PTR_ERR'
make[2]: *** [drivers/usb/gadget/r8a66597-udc.o] Error 1
make[1]: *** [drivers/usb/gadget] Error 2
make: *** [drivers] Error 2
root@10.0.2.17:/opt/mainlinekernel/git#

Maybe i should build only a module and load it with the "modprobe"?

What are my next steps?

With the best Regards. Pavel Goryunov.

Hi,

In the corresponding C file where you are getting the error add the statement #include <linux/err.h> and try building.

Thx,

Thank you for the fast reply. I dont really know why, but sequence of compiling changed.

Now i have such error:

CC drivers/video/console/vgacon.o
drivers/video/console/vgacon.c: In function 'vgacon_startup':
drivers/video/console/vgacon.c:508: error: 'PCIMEM_BASE' undeclared (first use in this function)
drivers/video/console/vgacon.c:508: error: (Each undeclared identifier is reported only once
drivers/video/console/vgacon.c:508: error: for each function it appears in.)
drivers/video/console/vgacon.c: In function 'vgacon_do_font_op':
drivers/video/console/vgacon.c:1068: error: 'PCIMEM_BASE' undeclared (first use in this function)
make[3]: *** [drivers/video/console/vgacon.o] Error 1
make[2]: *** [drivers/video/console] Error 2
make[1]: *** [drivers/video] Error 2
make: *** [drivers] Error 2

in ".configure" file line of 2.6.32 kernel looks like this "#CONFIG_VGA_CONSOLE is not set " in default case.

I also tried to change this line to such view "CONFIG_VGA_CONSOLE=y" and "CONFIG_VGA_CONSOLE=n"

So error appears over and over again. Maybe i should show my .configure file or some part of it?

Thanks a lot.

Hi,

If you want to disable VGA_CONSOLE support, do the following,

$#<linux directory>make menuconfig

go to Device Drivers====>>> Graphics Support ======>>> Console display Support=====>>>> VGA text console, Now unselect it,

and that wont build for you.

Thx,

Thanks.

So it does not matter if this option enabled/disabled or is not set.

Error appears in all cases.

Hi,

Are you still getting the same error's even after disabling it? What are your steps for building?

Thx,

Yes. Exact same errors in all cases. I checked twice.

Hi,

What are your steps for building? In worst case If you don't want the vga to be build,

go to Makefile in drivers/video/console and comment this line obj-$(CONFIG_VGA_CONSOLE) += vgacon.o

Thx,

Hello. Thanks for reply. Commenting a line helped me.

Now i have such error:

LD .tmp_vmlinux1
arch/arm/mach-davinci/built-in.o: In function `dm355evm_setup_video_input':
board-dm355-evm.c:(.text+0x29d0): undefined reference to `dm355evm_msp_write'
board-dm355-evm.c:(.text+0x29f0): undefined reference to `dm355evm_msp_write'
make: *** [.tmp_vmlinux1] Error 1

What you will recommend me?

Hi,

add the following statement,

#include <linux/i2c/dm355evm_msp.h> in board-dm355-evm.c

Thx,

I already have such line in "/arch/arm/mach-davinci/board-dm355-evm.c"

0 Prabhakar Lad over 13 years ago in reply to Pavel Goryunov

Hi,

Can you cross verify and check the declaration "dm355evm_msp_write" is present in include/linux/i2c/dm355evm_msp.h?

Thx,

0 Pavel Goryunov over 13 years ago in reply to Prabhakar Lad

In include/linux/i2c/dm355evm_msp.h ,i have such declaration of this function -"extern int dm355evm_msp_write(u8 value,u8 reg);"

So i guess here everything is fine.

Hi,

do make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

and just go to drivers---->>>Multifunction device drivers --->>>>>> [*] DaVinci DM355 EVM microcontroller select

Thx,
