Hi Tonci,

I would highly recommend upgrading to the 3.2.1 firmware and use the latest 3.2.1 configuration software.

** The 3.2.1 firmware fixed periodic corruption in the PC<-> MJLJ communications (while the engine is running) which can happen regardless of the software you are using.
** The firmware also significantly improves RPM stability. If you have a race car you really want this new firmware.

** The 3.2.1 configuration software improves communications through many fixes for USB->Serial adapters

3.2.1 firmware here: http://www.autosportlabs.net/asl_dist/mjlj/mjlJunior_V3.2.1.s19

I've tried to upgrade to v3.2.1, but it stops at this:''Waiting for HC08 reset ACK...'' so I presume that there is no bootloader on my motorola chip ( I did buy it programed from you about one year ago). I have tried upgrade from my old laptop that has serial port but it has windows 98 (can this be a problem?). How can I upgrade firmware if I don't have bootloader on motorola?

Edit: since when did you start to install bootloaders on motorola chips?

If you got the CPU pre-programmed, the bootloader is present- it would never go away. So you do have the bootloader installed.


sometimes the hc08sprg.exe is picky about USB->Serial adapters, but If your machine has a standard serial port it should work OK.

Are you following this sequence for writing the new firmware? Are you specifying the correct COM port?

(power down MJLJ)
> hc08sprg.exe COM1 mjlJunior_V3.2.1.s19
Waiting for HC08 reset ACK...
(now power up MJLJ)
..received 0xfc (good).

....programming sequence happens here...

Yes I have followed that procedure but it stoped at this:
Waiting for HC08 reset ACK...
can it be that it doesn't work with win 98?

I have not tested it on Win98, but it should work in theory. I use it primarily on Windows 2000.

Are you able to try a different computer?
