Dear TI members,
I have developed custom ACI motor driver with F28069.
I'm in trouble with serial flash downloader.
please take look at following capture of serial flash procedure
As you may see, download was not proceeded, just hold in this point, over 10 minutes, so I stopped.
Would you please let me know what is wrong with my trial ?
Best Regards,
Hae Ryong
Hi Sal,
Thanks for your response.
I have checked GPIO34 and GPIO37 as you commented.
please refer to following capture.
As you see, GPIO34 is always 'H', and GPIO37 is normally in 'H', and it went to 'L' with jumper in JP1 for flash programming.
I think, it seemed to go to bootloader mode correctly, becasue I have made LED blinking in my application, but LED is not blinking when I tried flash download
please take a look at the circuit of my custom board, let me know your idea.
my steps to download flash as follows
1. power off board.
2. put jumper on JP1 for bootloader mode when power up.
3. power on board
4. run serial_flash_programmer with proper serial connection.
5. programmer was hang as you saw in capture of this thread.
I have tried to search E2E to find similar issues, but I could not find proper one.
please help me to resolve the issue.
Best Regards,
Hae Ryong
