TMDXICE110: PRSDK RTOS - FLASHING PROCEDURE

Hi Karthik,

Did you set the baud rate to 115200 for the serial console? If you flashed the application correctly, when you power up the board, you should see the same message as you ran the application through CCS.

Hi Jianzhong, 

          I have checked the serial terminal settings, they are good. I checked  the same with the diagnostics application using the steps in prsdk developers guide. I was able to flash them using the am335x-evm bootloader but not with the amic110-ddrless bootloader. When doing the same for UART_basic example with am335x-evm bootloader I get this:

StarterWare Boot Loader
BOARDInit status [0x0]
SoC : [AM335X]
Core : [A8]
Board Detected : [AMIC110]
Base Board Revision : [UNKNOWN]
Daughter Card Revision: [UNKNOWN]
MCSPI Instance number: 0
Channel/Chip Select number: 0
The instance address is 48030000
offset = 0x20000, size = 0x8, dst = 0x402f9d50

Copying Header of the image
Copying image from flash to DDR
offset = 0x20008, size = 0x20008, dst = 0x4e20

After this my application does not load. Any suggestions?

Hi Karthik,

Sorry for my delayed response. The flash writer you're using, C:\ti\pdk_am335x_1_0_17\packages\ti\starterware\tools\flash_writer\spi_flash_writer_AM335X.out, may not work with AMIC110.

Can you try the Uniflash tool (https://www.ti.com/tool/download/UNIFLASH)? Download and install it and the flash writer for AMIC110 is:  uniflash_6.2.0\processors\FlashWriter\iceAMIC110\uart_iceAMIC110_flash_programmer.out.

Thanks,

Jianzhong

hello Jianzhong, 

When running the out file from uniflash, the following message is displayed.

"CortxA8: Loader: One or more sections of your program falls into a memory region that is not writable.  These regions will not actually be written to the target.  Check your linker configuration and/or memory map."

Hi Karthik,

After some more investigation, I believe there were two problems in your original procedure:

1. In step 2), you should use 0x80000000 in generating the application image:

C:\ti\pdk_am335x_1_0_17\packages\ti\starterware\tools\ti_image>tiimage.exe 0x80000000 NONE uart_example.bin uart_example_ti.bin

2. In step 3), You should use AM335x EVM bootloader:

Select option 1 and CHOOSE : C:\ti\pdk_am335x_1_0_17\packages\ti\starterware\binary\bootloader\bin\am335x-evm\gcc\bootloader_boot_mcspi_a8host_release_ti.bin 

I verified the procedure by myself and it worked fine for me.

By the way, when you build the CCS project, it will generate the application image for you. This is done in CCS post-build steps. The generated application image is: C:\ti\pdk_am335x_1_0_17\packages\MyExampleProjects\UART_BasicExample_iceAMIC110_armExampleProject\Debug\app. I used this one in my verification. You can try this one first and then try your step 2) with 0x80000000.

Hope this can help you solve the problem.

Hi Jianzhong,

     When using the "app" instead of the _ti.bin file, nothing gets displayed on the serial terminal.

     Also, what is the offset address to given when prompted in step 4??

Regards,

Karthik

Hi Karthik,

Use 0x20000 as offset address in your step 4.

Please also make sure you have a UART connection through the TTL-232R-3V3 serial cable according to AMIC110 ICE EVM Hardware Setup Guide.

Hi Jianzhong,

while loading the spi flash writer - spi_flash_writer_AM335X.out file and resumed, "[CortxA8] AM335X part detected." is displayed in the console

and the following prompts :

Enter Operation [1 - Flash ] [2 - Erase] :

Enter the offset [in Hex]:         

are not displayed. 

Help me in regarding this

Regards,

Karthik

Hi Karthik,

Please try to power cycle the board and restart CCS.

Regards,

Jianzhong

hello Jianzhong,

the issue still persist. 

what would be the followed up step?

Regards,

Karthik

Hi Karthik,

The flashing worked fine for you initially, right? What were the changes that caused it not working? Can you describe your system setup in detail?

Thanks,

Jianzhong

Hello Jianzhong,

Yes, The flashing worked fine for the ARM example project only.  when trying with the same Target configuration for other example projects, the process was not successful.

so did all the procedure from the start( creating new target configuration file-> hard reset-> connect to the core->  enable halt on reset -> System reset->run-> load the program)

from that the issue arised

CortxA8: Trouble Writing Memory Block at 0x80000000 on Page 0 of Length 0x7ff0: (Error -1065 @ 0x3D5A) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.4.0.00006)
CortxA8: File Loader: Verification failed: Target failed to write 0x80000000
CortxA8: GEL: File: C:\ti\ccstest\UART_BasicExample_iceAMIC110_armExampleProject\Debug\UART_BasicExample_iceAMIC110_armExampleProject.out: Load failed.)

&

Does Restart the ccs means? : Window -> Preferences-> Code Composer Studio -> Products-> add(verifying the components)-> restart ccs(would be prompted)

Thanks & Regards

Hi Karthik,

For those projects which didn't work, did you check and make sure they have same setting and configurations as the example project?

By restarting CCS, I just meant you close it and restart it.

Thanks,

Jianzhong

Hi Jianzhong,

I am currently checking for the example project provided by TI, there also same error occuring.

Is there any way to erase the flash apart from loading the spi-flash_writer_AM335x.out file?

Thanks 

Karthik
