Hi!

I have succesfully build the latest svn trunk, "uclinux-dist-trunk-svn-7780", with the latest toolchain. I am using a bf537-stamp board. But I am not able to boot the bord with this dist. During the boot I get this:

I have unchecked the choice "JFS filesystem support" in menuconfig->File systems, which default is built as a module. Otherwise I was not able to build the dist. Can this have someting to do with the boot crash?

are you using different baud rates in u-boot and the kernel ? all ADI boards default to 57600

Thank you for your answer!

The baud rate of u-boot is set to 57600. I can boot the 2008R1.5 release with this u-boot without any problem. I have also tested the newest svn-trunk u-boot and the same thing happen.

Is it possible to change the baud rate in the kernal or is it always default set to 57600?

I need to run the new svn-trunk release of uClinux because there is a bug fixed which set several spidev chip select at the same time.

the baud rate is controlled by you via your kernel command line in your u-boot env settings

i noticed you're booting an ELF ... dont do that. boot the uImage.

if it still fails, try this:

I can now boot the uClinux svn trunk, if I use the u-boot2009.01 and the uImage for uClinux. I still get some strange characters during the boot but the system seems to boot correct. The problem now and this is that only the spi chip select 5 is working in the board. My spi configuration is the same as on the 2008 release. In stamp.c:

#if defined(CONFIG_SPI_SPIDEV) || defined(CONFIG_SPI_SPIDEV_MODULE)

{

.modalias = "spidev",

.max_speed_hz = 1000000, /* max spi clock (SCK) speed in HZ */

.bus_num = 0,

.chip_select = 1,

.controller_data = &spidev_chip_info,

.mode = SPI_MODE_3,

{

.modalias = "spidev",

.max_speed_hz = 1000000, /* max spi clock (SCK) speed in HZ */

.bus_num = 0,

.chip_select = 5,

.controller_data = &spidev_chip_info,

.mode = SPI_MODE_2,

#endif

The reason why I run the svn trunk is that the spi chip select bug should be fixed there, but I can not get it to work here either. My spi devices is shown in /dev/ as expected but only the chip select 1 is working. Any one how know a what I am doing wrong or a sloution on this problem?

One error in the above post, it is only the chip select 5 which is working

sorry I was a bit unclear. With "not working" I mean when I put a oscilloscope on the chip select pins out from the stamp-board the only pin which has a visible chip select signal is the chip select 5. When I try to send and receive data on a nother spidev the scope do not show a chip select siganl on the corresponding CS pin on the board. But the clock and data siganls lookes fine on the scope.

I have two spi devices(use CS1 and CS5) and on the 2008R1.5 release the work with the cooresponding CS pin. But I could only use one at a time because when I was sending data to one of them the other devices CS also was activated. Then I was reading on the forum that this CS problem was solved in the svn-trunk.

I hope this was clarify the my problem. Thank you for your help.

Did you dissable the PIN 4 on SW5, which connects with SPI ssel 5 PIN?
