I see on the industrial Stamp9G20, which come with 128MB SDRAM, have in uboot:
basicargs=console=ttyS0,115200 mem=64M
Is there any reason why this isn't set to 128M?
No, there is no reason. It should even be set to 128M, otherwise Linux won't have the 128MB SDRAM. It was an error in the production process, which we have now corrected. Thank you for the hint.
