LP-AM243: [ERROR] XMODEM send failed

Tool/software:

Dear Sirs,

I am encountering some issues when trying to flash the AM243x LaunchPad. I have already tried the following three methods:

1. Using Windows Command Line with Boot Mode : UART mode
   
   
   • I edited the default_sbl_ospi.cfg file to specify the required appimage.hs_fs and appimage_xip.
     
     
   • Then I ran the following command:
     "python uart_uniflash.py -p COM8 --cfg=sbl_prebuilt/am243x-lp/default_sbl_ospi.cfg"
     
     
   • However, I got the following error:
     
     
     
2. Using UniFlash Tool with Configuration set to "AM243X (SERIAL)" and Boot Mode is also UART mode
   
   
   • Settings are shown below:
     
     
     
   • The following error occurred:
     
     
     
3. Using UniFlash Tool with Configuration set to "LP-AM243 (LaunchPad)" and Boot Mode set to DEV mode
   
   
   • Settings are shown below:
     
     
     
   • The following error occurred:
     
     
     

Is there any way to resolve this? Or could there be an issue with my flash?

Additional Information:
When the boot mode is set to QSPI Flash mode, I can see the following serial output:

Thank you,
