PROCESSOR-SDK-AM64X: xmodem protocol efficiency

Tool/software:

Hi,

I am running TMDS64EVM board without os.

I am wondering, why you choose to use xmodem protocol? it is not efficient and has no advantage compare to other protocol. eg: Z modem.

for stability, Z modem > X modem > Y modem

for transmit speed, Z modem > Y modem > Xmodem.

Thanks.

Hello,

The ROM is limited to XMODEM only. Once you are at the SBL stage, you are free to use the Y-MODEM protocol if supported in the SDKs.

The Processor SDK does use the Y-MODEM protocol to boot the A53 SPL & A53 U-Boot in the UART bootmode. The MCU+ SDK does not have the support for the same.

Prashant
