LP-AM243: LP-AM243x

Hi Dorel,

Could you please go through the Getting Started guide below and let us know if you are still having issues connecting to the LaunchPad?

I am trying out of box experience.

Error to connect to the target. XDS interface working OK

I thought this should work fine and fill out the Benchmark demo screen, correct?

Everything else is for testing and creating our own projects, later on,  I mean using the link to have the tools installed on the current machine

Thanks,

Dorel

Hi Dorel,

There are a couple known issues that could be causing this:

• There is a known issue with the out-of-box experience that prevents it from loading from within TI Resource Explorer - to workaround this you will need to open the out-of-box experience in a new tab or window. This will be fixed within the following week. 
  
  
• We've received reports that some of the LaunchPads from the first batch do not have the SOC initialization binary pre-flashed which causes the out-of-box experience to fail. You can check if your LaunchPad is one of these by connecting the LP to your PC and opening a UART terminal. Make sure your LP is set to QSPI Boot Mode. When powering on the board you should see the following output on your UART terminal if your LaunchPad is pre-flashed. If you don't see this then you will need to flash your LP as described here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html#EVM_FLASH_SOC_INIT

• Also, please make sure you have selected the correct serial port for the out-of-box experience, "XDS110 Class Application/User UART"

Please let us know if you are still unable to connect after trying the steps above.

I am able to build  a few example from TI with no error.

When I try to load into the flash I get this error:

MAIN_Cortex_R5_0_0: Trouble Writing Memory Block at 0x0 on Page 0 of Length 0x40: (Error -1065 @ 0x40) 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 9.4.0.00129)
MAIN_Cortex_R5_0_0: File Loader: Verification failed: Target failed to write 0x00000000

Any advice please?

I was able to run the default firmware and get communication working over UART with a character sent out every 2 sec.

Thanks,

Dorel

Can you confirm your LaunchPad is in QSPI boot mode as shown below? 

You should see the following output on the UART terminal, confirming the SOC has been properly initialized and is running.

  Starting NULL Bootloader ...

At this point you can connect to the R5s and load programs via CCS.

Hello Sahin,

I met the same situation, i tried the QSPI boot, no uart output in terminal, i confirm that i am using XDS110 User UART, 115200.

Then i want to try the UART boot to check the "CCCCCC" print, configure the boot switch to 1110000, there is no CCCCCCC in uart terminal either.

i tried in 2 boards, the same situation, it's strange.

Thanks.

Hello, 

We've recently discovered an issue which requires connecting the micro-USB JTAG cable after powering on the LaunchPad. Can you please try this if you haven't already and let us know if it helps?

Sahin

Hello Sahin,

I tried as you suggested, power up board by USB Type C first, then connect the Micro USB, still no CCCCCCC printing out in UART booting mode, i also try to reset the chip by SW1/SW2/SW3, no improvement so far.

Thanks.

Hello Sahin,

Besides the UART boot, i also can not launch the debug in CCS 10.04, it shows below, i select the debug window as R5_0_0.

Thanks.

Hi,

I tried , not working

Thanks,
