Just found a supply of older industrial-grade ARM based SBCs which
appear to support Linux. There may be quite a few available, and at low
CPU: Atmel AT91RM9200,
FLASH: 2 x 45DB642 (16M bytes total). RAM: 2 x K4S561632H (64M bytes total).
Ethernet Phy: KSZ8721BL (100M). MAC 00-04-E8-XX-XX-XX, which was
registered by IER, Inc.
At least 2 x RS232 ports, with MAX3243 buffers.
Full size USB-B socket (USB device, not host).
RTC: M41T00, with small backup cell.
White headers are 2mm pitch.
106 x 84mm including connector protrusions.
Board is 2007 vintage, and marked 'M93030B'
Various linux Distributions identify the unit as 'MACH_M93030'.
Found a UBOOT distribution, and references to MACH_M93030.
A full OEM hardware manual will be very useful, but nothing obvious pops up.
The 64-mega-bit question is of course how much effort is a board like
this worth to get it going ?
