Looking for ICS05J.S19 for old HC705J1A EvaL KIT

[elpenguino]

Hi Everybody,

this may be a long shot , but here goes. I am looking for the above named 's' record for an old JICS programming/development board from around 1996/7.

This S record is for a HSC705C8A but the development kit if for a HC705J1A. The C8A is used on the eval board to program J1A devices and to emulate/simulate the J1A in circuit.

The problem is some pins on some ports on my C8A have been 'popped' and I can no longer emulate the J1A in circuit. That means I have to program OTP J1A devices to see if the code is perfect , which is obviously not ideal.

I spent some hours searching the freescale website to no avail.

I'm well aware I should be migrating to a more current device but just wondered if I can easily keep this system in use longer.

Cheers,

Chris

Hi Mac,
shame the jig wouldnt allow export of the S record. In the manual for the JICS kit it specifically says in the troubleshooting section, that if the C8A needs replacement, programmed devices are available from Motorola, or you can download the S record from the BBS and do it yourself. It also says the file is available on www.design-net.com/ etc etc but I see that URL is now parked.

I'll have a play with the Kit and see if it is tucked away anywhere - it's not on the CD that came with the kit.

Nevermind....... didnt think it would be so easy ! 13 years in embedded is a lifetime :smileyhappy:
Thanks,
Chris

Thanks Tonyp,

thats great, although I'll have to figure out what to do with it next! You have mail..

Cheers,

Hi Elpenguino,

I've got three Jicsboot V 1.00 programmmed HC705C8s. Back in nineties, I took them out of JICS and replaced them by software I made to custom program and serialize J1As for production programmers.
I've got also the version for KJ1.

I'd be glad to receive an offer.

Cheers,

Celso

The S19 is attached (it was once up the P&E site for public download).  By the way, if you want a brand new J1A programmer board (P&E) I have one for sale, make me an offer off list.  (It was bought as spare but we never got to use it and we have dropped the J1A since long ago.)

Hello Chris, and welcome to the forum.

Are you able to verify that an unprogrammed devide is blank, and can you correctly verify the code within a device that has already been programmed.  If so, it may be possible that the programming operation will still work.  At worst, you may have to sacrifice one chip to prove whether this is so.

Assuming you already have the programming facilities for the C8A device, it might still be possible to read the code from the faulty chip, in order to clone the device.  I have previously been able to repair the M68HC705JICS board by this means, after the programming of the J1A devices failed.

Strictly speaking, the replacement C8A should be a special high speed version of the device, since a 7.37 MHz crystal is specified within the documentation for the board.  However, it is possible you may still achieve some success with the standard device.

Regards,

Mac

Hi Mac,

thanks for your reply.

Yes, I can still program my J1A devices quite successfully, so I haven't reached a showstopper yet. It looks like I soon will as the supply of them dries up.

I haven't tried to read out the C8A ROM code - that would take some work that I was hoping to avoid. I see the C8A device can 'program itself' so I was not going to huge extremes to solve this problem, just wanted to see if this ICS05J.S19 file was available.

Did you read the code out of the C8A with a commercial/universal programmer of some kind or did you use some homebrew hardware?

Cheers,

Chris

Hello Chris,

Actually I used an old Motorola evaluation board for the 705C8A.  This had the capability of reading the code from an existing target device, and storing in RAM memory within the board.  New devices could then be programmed, similarly to when the contents of RAM originated from a S19 file.  Unfortunately, the board did not have the capability of outputting a S19 file, based on the RAM contents.
