==================================================

 

I'v develop my project 6 months.My program all run in SDRAM. After OMAPl137 update to V2, I meet two questions.

 

Q1: sfh_OMAP-L137 halt at "Waiting for SFT on the OMAP-L137..." 

 

cmd: sfh_OMAP-L137.exe -targetType OMAPL137_v2 -flashType SPI_MEM -erase

 

Q2: After many tests, I downloaded my ais file to spi flash by using spiflash_writer_ccsv3.out.But it cannot startup normally.

    AIS file download steps

        step1: connect OMAPL137 arm core

        step2: download spiflash_writer_ccsv3.out

        step3: run,input "dspais", and then input my ais file path.

        step4: Wait to finish, and turn the board to spi0 bootmode.

 

    After pown on reboot, OMAPL137 startup abnormally.But When I connect it using CCS,and do "CPU Reset" and "Restart", it works fine.So the program in spi0 flash has been moved in SDRAM.

    I also used UartHost and uart tool to load program . It still can not run until CPU reset and restart.

 

 

I guess the command "Jump & Close" operate failed, but didn't find out the reason now.

    Added:

    1 I's sure my program is ok,because it can run on omapl137_v1(D800K001). 

    2 Omapl137 can only restart and run after program has been downloaded.My step is

              step1: open the project and load the .out file of release version.

      step2: run

      step3: halt and close ccs

              step4: disconnect dsp , then shut the board down.

              step5: power up the board, and wait program loading progress.

              step6: connect dsp,  view memory at c_init00,then  do "CPU Reset" and "Restart"

              step7: run again.
