  • Forum Post: Re: require dm355spi.pdf development document

    Bernie Thompson TI
    You make a good point, it appears that the driver is accessing reserved locations within the SPIFLG register, the current version of the DM355 SPI manual is SPRUED4b which has these error bits reserved. This is something I will have to look at internally, for now I would use the driver as is.

    BrandonAzbell
    The DM355 does support up to 3 SPI interfaces. Provided you get drivers for the BGW200 from Philips and port them to the DM355, you should be able to use this as a solution.

    BrandonAzbell
    The TMS320DM355 can support up to 3 SPI interfaces. This is because several of the pins of the device are multiplexed, therefore depending on the features you are using, you may only get 1 SPI interface supported. Please check the TMS320DM355 datasheet on the Product Folder for more details.

    Tony, Did you have any success with getting the SPI to work on your DM355? I am about to embark on the same and wondering how to make the MTD interface work as advertised to talk to the on board eeprom. Richard

    I want to use the tsc2046 to drive a touch screen by spi1 on dm365, but the spi driver doesn't permit to share the spi1int0/spi1int1,share with edma, with others modules. So when called request_irq in spi_prob, it always return error. How I can do to skip it? Must to use spi0?

    SPI boot does work. For initial programming of the SPI EEPROM I used the modified Spectrum Digital utility spi_load (came with the EVM) which I ran through the emulator. There are some errors in it, but it's a good starting point. One advise: uncomment the verification code and make sure what is...

    I have made some progress. Here are a few observations: 1. The document "IPNC Reference Design on DM36x, User Guide" says that one can build either a "release" build or a "debug" build (see step 13 in section 3.1.1). To build the release build, copy davinci_dm368_ipnc_defconfig_rel...

    During the development of our DM368 based HD video products, we were benefited a lot by constantly reading posts from the community forum at e2e.ti.com and frequently seeking help from TI engineers. As a result we were able to create quite a few handy utilities and even ported Android to DM368 on Leopardboard368...

    We have problems with our SPI-EEPROM. Sometimes the last written data is lost after reboot. We use the SPI driver of the PSP 03.21.00.04. It looks like it's a problem with the chip select. After SPI transfer, the chip select remains asserted. Although the driver writes 0x00ff to the upper 16...
