AM6548: programming FlashWriter on AM65xx Platform via TI's uniflash tool.

Hope,

I have tried this at my end and have been able to successfully erase the OSPI on the EVM.   Here is the detailed process on what I have done and have also tried to highlight some things that I found when using this process.

Steps :

1. Download and install the Uniflash version v.4.5.0 from http://www.ti.com/tool/UNIFLASH

2. Setup the CCS for AM65xx to configure DDR and load the DMSC firmware. Refer below link for detailed instructions

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/How_to_Guides.html#ccs-host-setup 

3. Connect the USB cable between USB2UART port (J42) of the board and host PC
Configure board for no boot mode ( SW2 all switches OFF, SW3 Switch 1 ON)

Configure the serial console application on host PC to connect to MAIN UART0 port
There will be four COM ports detected on the host PC. Connect to the first COM port out of four

4. Launch target config file for AM65xx platform and connect to A53 core.
Load the flash writer binary ..\uniflash_4.5.0\processors\FlashWriter\am65xx_evm\uart_am65xx_evm_flash_programmer.out to A53 core

5. Run the program and confirm that character 'C' is getting printed on the host PC sertial console. Make a note of the COM port number

Close the serial console, disconnect and reconnect the serial cable  to the host. Re-enumerate the port on the host.

6. Go to Uniflash root folder and run the below command to erase OSPI flash
dslite.bat --mode processors -c <COM Port#> -e 10000 -d 3 -o 0

Status 

OSPI_Erase_Log.txt

C:\ti\uniflash_4.5.0>dslite.bat --mode processors -c COM33 -e 10000 -d 3 -o 0
Executing the following command:
> C:\ti\uniflash_4.5.0\processors\ProcessorSDKSerialFlash.exe -c COM33 -e 10000 -d 3 -o 0

Erasing Flash....

Transferring Header information..
Header Transfer Complete!!
Flash Erase Success!

Hope this helps.

PS: Can you confirm that you disconnect the cable on the host and not on the board

Hi Rahul

thanks very much, I really appreciate your help.

but it still doesn't work.

step1 is OK. I have downloaded it.

about step2,my output in CCS is as below, does it meas that I have already configure DDR and load the DMSC firmware successfully?

and

step3~step6 are all the same as your answer.

but   when I execute dslite.bat --mode processors -c COM6 -e 10000 -d 3 -o 0

still remains Transferring Header information.. and cannot goes on.

and I run the SD card diag program to test OSPI

result is as below, does it means that there is something wrong with my board's OSPI flash? 

>PS: Can you confirm that you disconnect the cable on the host and not on the board

I disconnect the cable both on the host and board.

Hope,

Since we are not able to reproduce each others setup, I have created a video with screen capture to show this interface working with Uniflash 4.5.0 and AM654x  beta EVM. Please check the above to see that your steps match the same.

I checked with the development team if there are any known issues and they have the following questions:

• Is the port number confirmed to be Main SOC UART port ? Can you check in device manager that after you disconnect and reconnect you get the same port numbers?
• Is there a large time delay between when you launch. It appears the UART loader application run from A53 times out after 25 retries. IF this the case, I would recommend that you, reload the out file and restart the app on A53 as shown in the video
