I’ve just purchased the Le Potato AML-S905X-CC (v1) and this is my first post. I’ve tried to search about this question, but haven’t found any results. Although I’ve never used the Le Potato AML-S905X-CC board before, I have used similar boards such as the BPI M5 and the Odroid C4.
What I’d like to do, irrespective of any other possible alternative methods, is boot the Le Potato AML-S905X-CC over USB DFU mode using the amlogic worldcup protocol. I’ve done this with the M5 and C4 (using instructions provided for each). If similar instructions are available for the Le Potato AML-S905X-CC, please point me to them. I tried to wing it myself using the steps below. If there are no official instructions, perhaps someone will notice some error in my attempt as shown below.
After obtaining a wordcup connection to the Le Potato AML-S905X-CC, I ran these commands:
update cwr DDR.USB 0xd9000000
Transfer Complete! total size is 49152 Bytes
update write usbbl2runpara_ddrinit.bin 0xd900c000
Transfer Complete! total size is 32 Bytes
update run 0xd9000000
[update]:Run at Addr d9000000
AmlUsbRunBinCode:ram_addr=d9000000
at this point, the following is displayed over the serial port:

Then the next command is run:
update run 0xd900c000
[update]:Run at Addr d900c000
AmlUsbRunBinCode:ram_addr=d900c000
And the following additional text appears over the serial port:

And the following additional text appears over the serial port, but the boot has failed:
