  • Forum Post: Re: c6727 SPI slave boot mode problem

    TimHarron
    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...

    KarlLunt
    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...

    I solve this problem by writing tool that converts ccs file in compatible binary. And it works. My next problem is i2c slave boot. Cause my code have size more than on-board EEPROM size. How can I solve this problem?

    I made change on the biosusb keyboard hid dev example for sending and receiving 32 bytes data with PC. The memory need is reduced so the program can run on internal memory of c6745. The program run ok on evmomapL137 and can exchange data with a hid application on PC. But it do not work when I tried UART...

    AlanZhang
    Hi, We are trying to boot DM6437 from UART (mode=0x1000b, no hardware flow control). Using genAIS tool, we tested a small test program and loaded it into DDR RAM. It went through without CRC error (at least not reported by AIS). Then we tested a slightly bigger program. We constantly got "DATA...

    Fabion et Fronk
    Hello, we do have a question regarding the multiplexed GP0/HPI pins of the TMS320C6418 DSP. We are developing an universal DSP Board with this DSP and a MSP430F1481 microcontroller serving as host for this system. This µC should initialize the DSP via HPI16, whose pins are multiplexed with...

  • Forum Post: Re: OMAP137 HPI boot problem

    Joe Coombs
    Can you describe what's happening during/after boot? I'm guessing that you connect via the JTAG and check that your program data is correctly loaded (i.e. using a memory window in CCS). Where is the program counter at this time? Here are some general pointers for HPI boot: Make sure that...

  • Forum Post: Re: OMAP137 HPI boot problem

    Joe Coombs
    The most likely problem is that your HPI host is not properly signaling the OMAP-L137 bootloader with HINT. Per the bootloader app note, the appropriate sequence is as follows: Host reads HINT bit in HPIC register (must read as 1) Host clears HINT by writing 1 to that bit Host loads program data...

    Hi yes, i can do that. I added an assembler interrupt vector, that loads at 0x800000 (0x10800000 global space) and jumps to _c_int00, as we did in older DSPs. I am not sure if this was the right thing to do, I am not sure if the software is running yet. We also have a new issue: after issueing...

    Hi yes, I do. Is it possible to connect to the board using CCS and avoid a halt on connect? I mean - while the DSP is running (or not...) , I connect the CCS and maybe break the program execution to see where I am stuck. Also, I wrote Tom that we have a new issue: after downloading and (maybe)...

    Hello, I've written a bootloader for DSP6747 to be booted by ARM master (external device). Now, instead of writting a bootloader, I decided that it would be easier to add to a program that is to be uploaded the function that copies SDRAM to FLASH, when recognizes that FLASH is empty, and next...

    Matthias, Can you connect with an emulator after the boot has been reported as complete and see where the program is running? My first thought was that this is related to using a GEL file when loading under CCS, but you stated that it worked with and without GEL file. The only other thing I have to...

    Arye, Are you trying to boot from SPI flash? In that case, you should make sure that these conditions are met: Generate a binary AIS file (i.e. .bin or .ais; not .h) Store the contents of this file in the SPI flash starting at offset zero That should be all that you have to do. Simply...
