RE: With spectrum digital EVM1707+OMAP-L137 UI boards and XDS100v2, How to write Nand flash with CCS6

Hi Anna,

Please tell me what is the right spi image I should to put into SPI flash.

Have you Installed OMAPL137 SDK on your host machine & tried to flash pre-built binaries into flash ?

http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/368049

We can follow up your old post here.

Start CCStudio and connect to the DSP. Once done, connect to the ARM.-----------What does the DSP mean? AM1707 evm is a DSP or ARM? Thanks Anna

AM1707 -> It has ARM processor alone.
OMAPL137 -> It has ARM & DSP (DSP is master here ie it wakes up first and it would enable ARM next)

Is the SW2 setting 11110? I have AM1707 EVM

For SPI boot:
0101X
UARt
10100
Emulation or No boot mode:
11110

Thanks Titus,

I have a AM1707 EVM with AM1707 UI. So I do not have DSP function.
I have OMAP-L137_flashandbootutils_2_40 and DaVinci-PSP-SDK-03.20.00.014 on my host PC running window.
And I have another PC running Linux with OMAP-L137_flashandbootutils_2_40 and DaVinci-PSP-SDK-03.20.00.014 too.

I tried to flash SPI flash with pre-built binaries: ubl_AM1707_SPI_MEM.bin u-boot.bin (from OMAP-L137...), it flashed successful but getting failed messages when boot from SPI:
No magic number found. Looking for: 0x55424CBB, but read 0xA5DAFBC3.
SPI Memory Boot failed

Have you tried to use the following UBL and u-boot for AM1707 EVM ?

DaVinci-PSP-SDK-03.20.00.14/images/boot-strap/am17xx/arm-spi-ais.bin
DaVinci-PSP-SDK-03.20.00.14/images/u-boot/omapl1x7/u-boot.bin

Hi Anna,

mono sfh_OMAP-L137.exe -flash -targetType AM1707  ubl_AM1707_SPI_MEM.bin u-boot.bin [/quote[

Your heading says that you are trying to flash it to NAND memory, there is an error in your command . The default flash memory selected is SPI and not NAND.

To specify the NAND, use the command something like below.

Flash the memory with a UBL and application image - This will place the UBL at address 0x0 and an application image, such as u-boot, at address 0x10000. This is used for the AM1707 device.

• >mono sfh_OMAP-L137.exe -flashType NAND -flash <UBL binary file> <binary application file>

Additional options are shown below:

  -targetType         : Specifies exact target type within OMAP-L137 family (OMAPL137_v2 [default], OMAPL137_v1, C6747, or AM1707)
  -flashType          : Specifies exact flash type (default SPI_MEM)
  -p <COM PORT NAME>  : Allows specifying com port other than default 'COM1' or '/dev/ttyS0'.
  -h                  : Show help text.
  -v                  : See verbose output from OMAP-L137.
  -baud <BAUD RATE>   : Allows specifying baud rate other than default (115200)
  -APPStartAddr       : Changes entry point of application (default 0xC1080000)
  -APPLoadAddr        : Changes load address of application (default 0xC1080000)
 

Once any command is run, the "Waiting for BOOTME..." prompt shows. Power cycle the board or press the reset button to continue.
