What software is shipped with Medallion CPU modules?
We normally ship units with Linux preinstalled in the DiskOnChip (DOC) or NAND flash. The following table describes our SW architecture:
| Item | Location |
|---|---|
| Low-level boot loader | NOR flash (boot block) |
| Smart boot with monitor program | NOR flash block |
| Configuration info | NOR flash block |
| Linux kernel loader | NOR flash blocks |
| Customer's runtime, Linux image | NAND flash/DOC (compressed in a read-only file system) |
| Root file system, drivers, apps, data | One or more JFFS2 file systems in NAND flash/DOC |
| Optional, additional data | One or more JFFS2 file systems in NAND flash |
Our minimum flash configuration is 2 MB. It contains our proprietary boot loader/debugger and configuration info. It allows the unit to be recovered in case a program accidentally deletes the OS from the NAND flash/DOC. The initial boot loader uses the serial port as a console.
