Inspired by Joel's invitation, here's a call for a BSP port to
SPARCengine 1e board.
SPARCengine 1e is a SPARC V7 board in VME, circa 1991.
This CPU was used as a prototype for the ERC32 chipset.
The existing RTEMS ERC32 BSP does not work on SPARCengine 1e (see below).
Motivation for BSP port:
An ERC32 evaluation board can be found at $15-18K from Atmel or Tharsys,
whereas a used Force CPU-1CE or CPU-2CE boards are a mere $100 on ebay.
The ERC32 VME boards continue to be a viable choice of
radiation-hardened embedded systems for space applications.
Known problems with Rtems ERC32 on SPARCEngine 1e:
ERC32 BSP is in ELF format, whereas SPARCengine bootloader supports
Very little expert help can be found, the board is too old.
Original SUN libraries for this board are hard to find.
MMU got redesigned in ERC32.
VME support looks board-specific.
Hope to hear from someone interested.
