with a new TX2 module I noticed a new revision of the module. Revision D01 instead of B02. The image is based on R28.1.
According to PCN (PCN204840) the RAM (or better to say the BOM) has been changed and the module may contain the old RAM IC or the new one from Hynix.
Is it possible to detect the vendor of the RAM based on the serial number or with a command? I tried with dmidecode first, but it doesn’t work properly.
