Dear All,

Attached is an updated version of USBDM for JM60 (see earlier post).

It now includes support for Flexis (Coldfire V1) parts.  Experimental!

I note that there has been an "official" update of the OSBDM so this may now be moot.

bye

Re: Bootstrap for JM60.

I can't install the bootstrap example code on WinXP SP3.  It appears to require WinXP SP2 or Vista.  It isn't that much interest in any case since it doesn't get around the problem of the initial programming of the JM60.  If you can program it once presumably you can do it again :smileyhappy:

Thank you so much for this marvelous piece of work :-) I will try to build one when my JM60 samples arrive. I have a Multilink to program it with. I'm trying to help the Amateur Radio operators ( Hams ) here in Austin to get started with S08. Your work is wonderful and will certainly help us here to develop emergency radio equipment for the Red Cross.

Regards,

Dear pgo,

Please can you confirm that the USBDM_JM60 project can be installed into a JM32? When I look at the map file, I think it implies that the total firmware footprint is less than 11kB.

I just want to be sure before ordering parts, the JM32 is cheaper, and the JM16 still seems to be "not quite available for purchase".

Sincerely.

Dear Marksl,

I don't have a JM32 or JM16 to be able to test.  However, I believe the three chips are the same apart from memory size.  It does fit in 16K so should be usable with JM16 or JM32.  Changing the target on the Codewarrior project to JM16 and then  downloading to a _JM60_  confirms this but it's not a complete test.  (If you change the target in the project you will need to change the .prm file slightly - Increase the stack size and add Z_PAGE to the segment list.  See the existing .prm file).

Finally,  why are you using the JM?  It is rather easier to construct and program a JB16 version of the OSBDM and it's cheaper.  I only provided the JM60 version for the die-hards!

bye

Dear pgo,

Indeed - I only recently noticed that the JM* version seems to have an identical circuit to the JB16 version. As soon as I've been paid for my current project I intend to build your JB16 design.
I am glad to see you recommending the JB16, too - since I already have a few samples.

By the way, please check your private messages - I have a request there for you.

Thanks.

Hi, I'm a die-hard :-) I am very pleased with the circuit and software which I built with parts laying around. I used a 74HC125 dip and a 2N3904 and 2N3906 for the power on/off circuit (3.3volts only). I am able to link up with an MC9S08QD4 quite readily and I love it.

Here's my question. When I turn on the Periodical Update for a Ram variable it returns 0xFF's while running. As soon as I halt the process, the correct value appears for the variable. I wonder if the hardware is at fault or perhaps that particular function may have a bug. I've attached a dump of the commands, and as you can see the periodic update returns FF's but the correct value is retrieved after the Halt. Thanks very much for your assistance, and I really appreciate your JM60 project.

Regards,
John H. Fisher

Forget my previous message about periodical updates on watch variables. It seems to be working fine with the MC9S08QG8. I guess it is a function of the QD4.

Dear All,

Attached is an updated version of USBDM for JMxx (see earlier posts).

It now allows firmware updates using in-circuit-programming over USB.  This doesn't avoid the problem of needing a BDM to do the initial programming but does allow later updates without a bdm.

A version for the JM16CLC is also provided as well as one suitable for JM16/32/60CLD.

bye
