Enhancements
Memory Retention
FlexROM III uses SRAMs to store the code image. If you wish to cycle the target power to see the target
execute from power up, you will need to connect an external power supply to the emulator to maintain the
SRAM contents during the power outage. The emulator will retain its contents as long as EITHER target
power is applied OR external power is supplied to its power-in connector. The external power must be a
regulated 5VDC at 300ma or more.
Faster Downloads - Turn Off Verify
After you have used the emulator for a while and gained confidence that it is loading reliably, you can add a
/V0 parameter to tell the loader to skip the verify operation. This will reduce your load times by over 75%!
FlexROM III is optimized for the fastest possible downloads. Therefore, the data stream FROM the HOST
TO FlexROM III is much faster than the reverse direction.
If you ever wish to verify the CURRENT contents of FlexROM III’s memory against a file, simple do a load
with a “/V2” option (verify ONLY).
Increase 16bit Transfer Speed
The 16bit loader (RTLOAD16.EXE) is capable of over-running some printer ports. To allow proper
operation with ALL printer ports, the 16bit loader includes a SPEED parameter. Once basic functionality is
established, you may choose to speed-up your 16bit downloads. The download speed defaults to its slowest
setting to insure compatibility with all printer ports. The self-test program does a reliability test at a
specified speed setting. Re-run the FR3TEST program with a faster speed setting (lower /Dx number). If
the reliability test shows that the system is reliable at this speed, you will be able to use this same parameter
on the program.
Error Detection and Correction
If you add a “/C” parameter to the load command, the loader and Flex ROM II will generate and verify
checksums on each packet. In addition, if an error is ever detected, the packet will be automatically re-sent.
This adds about a 5% overhead to the transfers.
This is much more efficient than doing a complete verify of the SRAM contents against the load file and
still provides a high degree of confidence that the download is valid.
