There is no reference to an "X1" version - are you reading the markings correctly?
I did make a mistake, the rev is "2X". But I have the official errata and there is no reference to it.
the 4th line on both of my devices is "+D2502X" Using the errata the 4th line should be "xxYWWxR[x]" There aren't enough digits on my devices, but it appears they are 2012WW50 silicon, rev 2 and "X" for the boot loader.
Reading the device ID with MagicFlash returns a boot loader of 13.2, so I'm assuming the 2X version is a pre-release of the 2A silicon and should behave the same.
I can read the serial number, Is there any listing of what serial number ranges correspond to which silicon and boot ROM verisons?
