How can I write the DM365 flash?

Other Parts Discussed in Thread: CCSTUDIO

I have the 365 evm.When I powered on, there were nothing on the console.

Then I used the files "\evmdm365_v1\tests " to test the board.And all the test passed include the uart .

Then I thought maybe there were no program in the NAND flash.

I used the \dvsdk_2_10_01_18\PSP_02_10_00_14\board_utilities\flash_utils\DM36x\CCS\NANDWriter to rewrite the flash.

But when I used CCS loadprogram "NANDWriter_DM36x.out" , it told me " File not Found boot.asm".

I tried to build the sources of NANDWriter,it told me

"[nandwriter.c] "C:\CCStudio_v3.3\tms470\cgtools\bin\cl470" -g -fr"C:/CCStudio_v3.3/boards/evmdm365_v1/flash_utils/DM36x/CCS/NANDWriter/Debug" -i"C:/CCStudio_v3.3/boards/evmdm365_v1/flash_utils/DM36x/CCS/NANDWriter/include" -i"C:/CCStudio_v3.3/boards/evmdm365_v1/flash_utils/DM36x/CCS/NANDWriter/../../../Common/ccs/include" -i"C:/CCStudio_v3.3/boards/evmdm365_v1/flash_utils/DM36x/CCS/NANDWriter/../../Common/include" -i"C:/CCStudio_v3.3/boards/evmdm365_v1/flash_utils/DM36x/CCS/NANDWriter/../../../Common/include" -i"C:/CCStudio_v3.3/boards/evmdm365_v1/flash_utils/DM36x/CCS/NANDWriter/../../../Common/drivers/include" -d"_DEBUG" -d"SKIP_LOW_LEVEL_INIT" -me -mv5e --abi=eabi -@"../Debug.lkf" "nandwriter.c"
ERROR: bad argument to option --abi: should be one of { ti_arm9_abi tiabi } "

Could you tell me what can I do next ?

Now ,I download the ti_cgt_tms470_4.5.2_setup_win32.exe,and I can compile the source.

But I test the nand flash using nandflash-lower or nandflash-upper,the CCS stops at the SW_BREAKPOINT,because the dst is 0

for (j = 0; j < (16 * NANDFLASH_PAGESPERBLOCK) /*NANDFLASH_PAGES*/; j++)
{
     nand_readPage(j, dst, NANDFLASH_PAGESIZE);
  status = 0;
  if (dst[0] != (j & 0x000000ff))
      status = 1;
        if (dst[1] != ((j & 0x0000ff00) >> 8))
            status = 1;
        if (dst[2] != ((j & 0x00ff0000) >> 16))
      status = 1;
        if (dst[3] != ((j & 0xff000000) >> 24))
      status = 1;
  if (status)
  {
      errors++;
  }
  if (errors)
  {
//      printf("Error on page %d\n", j);
   SW_BREAKPOINT;
        }
}

I had the same issue come up a while back; see http://e2e.ti.com/forums/p/8254/32282.aspx#32282

I'm having the same trouble with my new DM365 EVM - empty NAND flash. It seems like a common problem from some of the other posts. And yes, when set to boot from UART my board does output the test strings like Juan suggests.

Can someone post compiled versions of sfh_DM36x.exe and slh_DM36x.exe? (for either windows or Linux) I don't have CCS 3.3, and need to get my board running immediately. I've built UBL and the kernel just fine. I just need to get them onto the board.

Can I use CCS 3.2 to compile these or do I need 3.3?

Thanks!

You should not need to recompile anything as the flashing utilities already come pre-built as part of DVSDK. However, you will need CCS 3.3 along with JTAG to flash the EVM as the sfh_DM36x.exe and slh_DM36x.exe utilities are not available yet. The main reason you would need to rebuild CCS or UART (when it becomes available) flashing utilities is to add support for a new NAND flash device to support your custom board.

So to be clear, my options for programming a blank NAND flash on a standard DM365EVM are:

Buy a CCS-supported JTAG programmer (don't have one) and program the FLASH
Wait for the UART utilities to be completed
RMA the board to SD and have them program it using option (1)

When will the UART utils be ready?

With all the DM365's cool and varied boot options, is there no other way to program the FLASH?

Can I use a Green Hills Probe JTAG box to program the FLASH via JTAG, with or without CCS?

Thanks

Unfortunately, at the present time, options 1 is probrably the only feasible option. I am not sure if SD will flash the board for you (option 3); I believe RMAs are used primarily for boards with bad hardware, but you can try.

There is no timeline yet that I know of on when UART flashing utility will be ready for DM365 and support for other bootmodes may also soon follow.

Unfortunately, I am not familiar enough with GHS tools to determine if they will be able to run CCS generated executables such as UART utils; if these tools are using same tool-chains, it may be possible but this is a better question for GHS.

I have sole the problem.

1.update the ccs3.3 buildtools. see:http://wiki.davincidsp.com/index.php/How_to_update_CCS_ARM_cgtools_to_build_the_DM365_ubl_in_CCS_3.3.

Then ,rebuild the source.,There will be no error happened.

2.loadprogram "NANDWriter_DM36x.out" , it told me " File not Found boot.asm".cho0se :"NANDWriter_DM36x.map".

3.OK!

You can get sfh_DM36x.exe here:http://arago-project.org/files/releases/davinci-psp_3.1.0.0-phase3/board_utilities/serial_flash/dm365/

But there are some problems with it.

there is the reasons as Bernie Thompson told me:

Note that the DM365 original silicon had issues with the serial boot process, where the serial boot loader would fail as it was setting the UART clock wrong, this being said a utility like sfh_DM36x will only work on the latest silicon rev 1.2 or later. This being said, before digging into this you may want to verify your particular board is using the latest silicon, chances are that unless it is very new that it is older silicon. If your silicon is too old than you may want to consider reflashing alternatives like through JTAG (CCS) or through a SD card.

As to the actual utility, the sources for the serial boot utilities are all included with the PSP collateral package available from the DVSDK download site at http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_2_10/latest/index_FDS.html.

As to the UBL and U-Boot you may want to ask the board manufacturer (Appro) about what versions they recommend, there are UBL and U-Boot images/sources in the DVSDK mentioned above however they are meant for the DM365 EVM board and may not function properly on the Appro DM365IPNC board.

Hi all,

I am a newbie to this forum and evmdm365. I have evm 365 and found some test applications undeat r the directory \evmdm365_v1\tests... I compiled source fiels under sd0 in linux environment and generated the exe. Transfered that exe in to evm using tftp..

But the probelm is when I execute that exe in the evm365 i get the segmentation fault. I understand that the exe is trying to do some initialization at the startup ( PINMUX3 &= ~0x00600000; Wiggle I2C clock line to make sure devices aren't hung ) and this throws segmentation fault as this is trying to access the hardware register from user space.

Here are my questions,

1. Do we need to follow any other procedure to port and test the sample applications in evm365.

2. Do we need to modify the sample application code provided with the evm 365 to access the hardware registers from user space.

Thanks in advance,

Charan
