Issue in SPI0 and AMS3 multiplexing of PORTG in BF51x

analogvm-admin@analog-vm.hosted.jivesoftware.com — Fri, 17 May 2013 09:41:31 GMT

Hello all,

I want to use the SPI0 port of the BF51x. However, it is in the same multiplexed group of AMS3. I am using a NOR parallel flash for my rootfs and vmImage. So, I think I cannot use both at the same time. I do get an error on booting, that the pins confict. I have commented out the #ifdef line in the __init of ezbrd.c board file, allowing the request for AMS3 as well as keeping the SPI0 enabled. However due to this, the bfin-spi.o module does report an "Reqeusting peripherals failed" error. So, i presume the SPI won't work. However, I think this happened because I enabled the AMS3 request in the init of ezbrd.c. So, this shouldn't cause u-boot from booting the image, just because it cannot find a 4th partition. But, this does happen and the visibility of the NOR flash is reduced from 4096K to 3072K. Due to this, the part of the rootfs(which is residing in the 4th partition) is not visible, hence the kernel panics and gives out an error of "init not found". I have also added some printk's and debug messages in the board file and bfin-spi module. I am using a custom board based on the ezboard, but a stripped down version of it. I am pasting the boot log here:http://pastie.org/7919784

Any help is appreciated.

linux defconfig trouble

analogvm-admin@analog-vm.hosted.jivesoftware.com — Wed, 15 May 2013 12:10:57 GMT

Hello,

I'm trying to create a complete "buildroot" configuration, of my own.

I'm using the newest release: blackfin-buildroot-2012R2-RC5.tar.bz2 + uclibc_full.

Buildroot defconfig can be created with "make savedefconfig". (And copied to the config folder)

The linux config can be created with "make linux-savedefconfig".

The buildroot config defines where to find configs for busybox, linux, etc.

I'd like to place my linux.config in the vendor folder (as suggested by the Buildroot documentation).

Eg. using AnalogDevices config as template, I've copied the linux defconfig to "board/AnalogDevices/blackfin/linux.config". Then I've set the "Using a custom config file" in menuconfig and the "Configuration file path" to "board/AnalogDevices/blackfin/linux.config". There're several other configs (eg. calao_usb_a9g20_lpw_defconfig), that does it likewise.

But it doesn't work! I run the following:

make clean

make distclean

make pch-bf526_defconfig

make menuconfig

make linux-menconfig (this one breaks)

It fails with:

What am I doing wrong?

I've attached my Buildroot defconfig and my linux defconfig. The rest is the same as the bf526-ezbrd-fdpic_defconfig

Post image script option missing

analogvm-admin@analog-vm.hosted.jivesoftware.com — Thu, 16 May 2013 09:06:01 GMT

Hello,

The buildroot documentation mentions an option for a "Post Image Script". A script that will be executed after the images has been created.

I cannot find this option in the newest release. It's supposed to be called "BR2_ROOTFS_POST_IMAGE_SCRIPT"

Documentation is here: http://buildroot.uclibc.org/downloads/manual/manual.html

can not compile cairo on bf609-ezkit

bf526-ezbrd-fdpic_defconfig can't compile

analogvm-admin@analog-vm.hosted.jivesoftware.com — Mon, 13 May 2013 14:27:22 GMT

Hello,

I'm downloaded the blackfin-buildroot-2012R2-RC5.tar.bz2. I'm using the uclibc-full buildchain.

I've tried out the bf526-ezbrd_defconfig and that seems to work.

Then I've tried the bf526-ezbrd-fdpic_defconfig and that doesn't seem to work.

I've attached a "make 2>err".

If you disable all libraries in menuconfig (Eg. Speex etc.) it seems to compile.

Can't compile openvpn

analogvm-admin@analog-vm.hosted.jivesoftware.com — Wed, 08 May 2013 14:57:37 GMT

Hello,

I've just downloaded the new 2012-RC2 dist + toolchain (full). I'm using the bf526-ezbrd_defconfig. (It compiles fine, when using defaults.)

I've then added "openvpn" through menuconfig. And it doesn't compile. The error message is:

It nags about "libdl" I think. Isn't this supposed to work?

There's no "libdl" in menuconfig btw?

Is there a user space example for using the gptimers device driver?

analogvm-admin@analog-vm.hosted.jivesoftware.com — Mon, 15 Apr 2013 21:35:23 GMT

My application requires the use of the BF537 timers 2 and 3 driven by an external clock. Is there an example somewhere that initializes these timers?

Best Regards,

Output the PWM signal

analogvm-admin@analog-vm.hosted.jivesoftware.com — Sun, 12 May 2013 06:22:41 GMT

now am using the example driver at :

drivers/char/bfin_simple_timer.c

and the driver compile well. And I had insert the modle in my BF537 (running uclinux)

it dose well .

next ,i write a applications to use the driver to produce the pwm .

the application is follow:

#include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <sys/ioctl.h>

#include <sys/types.h>

#include <sys/stat.h>

#include <fcntl.h> //open function

#include "pwmapp.h"

int main(){

int fd,result;

fd=open("/dev/timer7",O_RDWR);// timer7 linkto minor=7

if(fd==-1)

return 0;

result=ioctl(fd,BFIN_SIMPLE_TIMER_SET_PERIOD,3);

printf("ioctl %d\n",result);

result=ioctl(fd,BFIN_SIMPLE_TIMER_START,3);

printf("ioctl %d\n",result);

//result=ioctl(fd,8,3);

while(1){

}

return 0;

}

and I run this application. but the pin cannot output any signal.

I read the bf537 datasheet: it said:

"Every timer has a dedicated TMRx pin that can be found on port F ,If enabled, the TMRx pins output the single-pulse or PWM signals generated by the timer. "

And the datasheet says timer7 pin is PF2.

so I test the PF2 pin this is my port:(GPIO_UART1TX_PF2)

BUT THIS port cannot test any output.??

Booting of BF548 with uImage and Rootfs.tar

analogvm-admin@analog-vm.hosted.jivesoftware.com — Wed, 08 May 2013 15:44:18 GMT

Hello.

We are using BF548 and buildroot (blackfin-buildroot-2012R2-RC5.tar.bz2). We are trying to boot from sd card and have disabled the "Initial RAM filesystem and RAM disk (initramfs/initrd) support" option in linux-menuconfig hoping that we can reduce the boot time. But when we load uImage and Rootfs.tar in sd card and try to boot, we are getting the following message on the console

Unknown command 'root=/dev/mmcblk0p1' - try 'help'

And the booting is getting struck up after the following message,

[ 0.380000] musb-hdrc: version 6.0, ?dma?, otg (peripheral+host)

[ 0.388000] musb-hdrc: kernel must blacklist external hubs

[ 0.396000] musb-hdrc musb-hdrc: USB OTG mode controller at ffc03c00 using DMA, IRQ 82

Our boot argument is:

bootargs=root=/dev/mmcblk0p1 rw mem=96M max_mem=128M$ clkin_hz=25000000 earlyprintk=serial,uart1,57600 console=tty0 console=ttyBF1,57600

bootcmd=run mmcboot

mmcboot=mmcinfo;mmc rescan 0;fatload mmc 0 $(loadaddr) $(ramfile);run ramargs;run addip;run add_usb_args;bootm

Any suggestions to get over this error??

Thanks.

Nikhil.
