  • Forum Post: Re: SPI configured with dMAX

    TimHarron
    Sneha 1) If the peripheral devices only supports 32bits tranfer over SPI and 6727 SPI at max supports 16bits trasnfer, is there any way to have communication between them? (my limitation is the transfer should happen using dMAX) Because the SPI peripherals are only programmable to accept between 2 and...

    Why not do this: Assert the chip select Do two 16-bit transfers. De-assert the chip select. From the perspective of the signals, I don't think you could tell the difference. Just make sure to do the transfers in the right order. If the slave is expecting MSB-first, then you would need...

    Harbour
    Hi, Anybody succeeded booting c6727 from SPI host (in SPI slave mode) ? According to spraa69c there are 3 phases : 1. SWS 2. POS 3. OS I'm using ARM board, wich has SPI connected to DSP and RS232 connected to Linux PC, so all data is logged. I see that SWS is passed but POS is stucked in N number...

    Hello, There are several Advisories in the C6727B Silicon Errata related to the SPI (slave) peripheral - have you checked into these? Harbour 2. Is there any 16 bit SPI slave boot mode examples available from TI ? Pdf mentioned has only 32 bit flash examples. I believe there are only 32-bit examples...

    This is a rough article you point out, it points out some deficiencies that do exist for the C672x devices that do cause problems though some have gotten better and some can be avoided; TI still strives to support the devices better. What I really wanted to point out here is that if you want the rev...

    Hi all, I have a Lyrtech EVMDM648 equipped with a TMS320DM648 dsp, and I need to write a SPI interface between the dsp and a SPI EEPROM (ATMEL730 25256A). The board mux settings (not the DSP mux settings) between UART and SPI are surely correct (I had to turn off a dip switch); furthermore, i verified...

    When you OR the value of 0x5 into SPIDAT1 what guarantee do you have that the lower 16 bits are not already 0xFFFF? Note the following from the SPIDAT1 field description on page 29 of the SPI User Guide : When data is read from this field, the value is indeterminate because of the shift operation. The...

    Spot on, Adriaan! The SET command does, indeed, require transfer of the four words to the DSP in an order that differs from the order in which they are written to the AIS file. Note that the sample implementation (em_protocol.c) in TI's BootUtils folder does NOT alter the order of the words when...

    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.

    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.

  • Forum Post: Re: about SPI of DM355

    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.
