Would you post your register settings for the PAD configuration for SPI4?  We can at least start there and determine if everything is in order.

The register which controls mcspi4_somi is CONTROL_PADCONF_MCBSP1_DX at 0x48002190.  Just a quick thought, but you should make sure the INPUTENABLE bit is set.

This is the dmesg output from my printk in the mcspi driver (specifically the omap2_mcspi_txrx_pio function).

[   72.464597] (>")> omap2_mcspi_txrx_pio   MCSPI_CHxCONF = 001313D4
[   72.470761] (>")> omap2_mcspi_txrx_pio   CONTROL_PADCONF_MCBSP1_DX = 01010001

I know that the CHxCONF is set for rx only mode.  The system sends out a byte then reads in two (as per the tsc2046 requirements).  Again, the correct signals are on all four lines for the spi4 and I have verified that it is physically connected correctly by toggling GPIO and scoping the lines.

Sorry I hadn't gotten to this.  Do you have any status update on your efforts to receive on the SIMO input?

We worked on it for another day or so before we just modified the touchscreen driver to bitbang the spi.  I'm going to keep an eye on it because we would prefer to use the hardware but I'm pretty hopeless.

Have you seen recent activity on the beagleboard@googlegroups.com mailing list regarding MCSPI functionality?

It appears Mr. Balister has made some progress in this endeavor as it relates to the Linux kernel having its own PINMUX setup and other configuration beyond what something like u-boot is doing.
I'm not sure if this is directly applicable to your efforts, but given the subject of the RX path always receiving 0s is the same, it seems plausible to be related.

Kevin,

I had the same problem and resolved it the same way you did... I spent about 3 days working on the SPI interface to my LCD controller (on a CSB740 board).  Verified with scope that all pins were functioning correctly, but never saw a thing on the rcv register (all zeroes).  Then spent 15 minutes implementing it with bit-banging and it worked just fine.  Sure would like to know the secret (assuming its not a silicon bug in the OMAP35xx).  In my case, I'm not using u-boot or linux, this is a port of MicroMonitor.  Regardless, it sure would be nice to switch back to SPI mode in place of the bit-banger.

If you ever get an answer on this, I'd sure like to hear about it.

Thanks

Ed

Is the INPUTENABLE to the mcspi*_clk enabled?  Although the functional clock to the McSPI interface is on inside the device and clocking the TX state machine, the mcspi*_clk pin is wrapped back inside the device to actually sample the mcspi*_somi input.

Brandon,

Hmmm... I missed your earlier point regarding this  :-(.

I see that it isn't set in my code.  I'll try changing this and let you know (can't do it till tonight). 

Thanks, Ed

Brandon,

Thanks much... I made that change and that fixed it...

I had this exact same problem and struggled for days. It needs to be explaned in the data manual the clk pad needs to be configured as input.

I lost 4 days on this problem trying to program McSPI1 from the C64x+ side.  I concur that TI needs to add this crucial detail to the McSPI manual!!

Hi,

Can anyone please let me know why pull down resistor is required on McSPI1_CLK line?

I have seen in beagle board, there also pull down is given.

Please let me know.

Regards,

Murugan

 

AFAIR the pull down on the McSPI1_CLK line on BeagleBoard is only for BeagleBoard revision detection. The pin on Beagle isn't used in SPI-mode, but in GPIO-mode (GPIO171) together with GPIO172 for board ID detection. Using the pin in SPI-mode won't require the pull down.

Best regards

I try MIDAS v2.0 following web sitehttp://processors.wiki.ti.com/index.php/MIDAS_Ultrasound_v2.0_Demo

I think that I succeeded compile in everything except touch screen.

I try Touchscreen Setup follow web site blow.

Touchscreen Setup

MIDAS utilizes the tslib library for touchscreen support on the OMAP3530 EVM. This section will guide you through setting up tslib.

       1. Install required packages on host

                   host $ sudo apt-get install autogen autoconf libtool

        2. For cross-compiling, define environment variables in ~/.bashrc on host as:

                     export CC=/home/<username>/arm-2009q1/bin/arm-none-linux-gnueabi-gcc
                     export CXX=/home/<username/arm-2009q1/bin/arm-none-linux-gnueabi-g++
                     export CONFIG_SITE=omap3evm.autogen

        3. Download the source files for tslib from here and save it at ~

         4. Untar the source

                       host $ cd ~host $ tar xjf tslib-1.0.tar.bz2

           5. Configure tslib

                        host $ cd ~/tslib-1.0
                        host $ ./autogen.sh
                        host $ ./configure --prefix=/home/<username>/workdir/filesys --host=arm-linux-gnu

           6. Comment the line ‘AC_FUNC_MALLOC’ in ~/tslib-1.0/configure.ac

           7. Comment ‘#define malloc rpl_malloc’ in ~/tslib-1.0/config.h if it exists

       

           8. Build and install tslib

                          host $ make
                          host $ make install

 

             9. Edit ~/workdir/filesys/etc/ts.conf to use linux layer event interface by uncommenting ‘module_raw input’

             10. Modify the device’s startup script to export the required touchscreen related environment variables.

                  Add these lines to the file ~/development/workdir/filesys/etc/profile:

                               export QWS_MOUSE_PROTO='Tslib:/dev/input/event1'
                               export TSLIB_CALIBFILE='/etc/pointercal'
                               export TSLIB_CONFFILE='/etc/ts.conf'
                               export TSLIB_CONSOLEDEVICE='none'
                               export TSLIB_FBDEVICE='/dev/fb0'
                               export TSLIB_PLUGINDIR='/lib/ts'
                               export TSLIB_TSDEVICE='/dev/input/event1'

                 11. Remember to run ‘ts_calibrate’ on the target the first time you start the board, to calibrate the touch screen.

I inputed command ts_calibrate and I get some message blow.

I'm looking for "Could not find exacpt pixel clock" at google and e2e.ti.com.

I found a TI member as same error message. ( http://e2e.ti.com/support/dsp/omap_applications_processors/f/447/t/94126.aspx )
