S12DP256, no Bootloader with menu, no D-BUG 12

[Fruity]

Hi,

I'm a student who is working at the moment on a HCS12 Board (Dragon 12) with CW 3.1.
I have some problems and i hope somebody can help me.

The first problem is that i'm not getting a menu in a hyper terminal from the Bootloader. When i flash some examples with CW (hi-Wave) they get in the flash 0x4000 and run . But opening a the hyperterminal (COM1,(9600/.../ I tried all),8,N,1,XON/XOFF) I don't get a menu.

The other problem is that i don't have a D-BUG12 Monitor on the µC. I have downloaded the software from Freescal but I can't flash the sourcecode. Here is the .s19 file

The download start's in hi-wave but at this codesection i get an error.
Memory 398000 .. 398002 is not exsisting/available.

I think the bootloader on the board is not understanding that on this codesegment must be a page-change (38 to 39).

So i hope someone can help me.

Hi,

first thanks for your answers. But your files couldn't help me. I get the same error message only on a other adress. You can see my error windows at the attechment.

[kwik]

What kind of program is giving you this message?

If you buy a BDM from Wytec ,you can restore both the bootloader and Dbug12 ....I think someone has overwritten the bootloader ....

Hi,

for flashing my programm i use Hi-Wave in association with CW 3.1.

I think that i lost the DBUG12 and Bootloader but why can i flash my testprogramms (blinking LED) an so with the GDI Interface?

I would not buy a BDM because it's a EVB from school and i don't wanna pay it because the EVB is not my.

Hi Fruity,

It sounds like you are using a Hi-Wave BDM debugger. That would most likely have erased D-Bug12 bootloader. Since the Hi-Wave BDM works for at least one program, there is no reason for any bootloader unless you need to use it somewhere with only HyperTerm (or other terminal), which perhaps is the case.

The trick might be to tell Hi-Wave that you want to load the S19 file containing S2 records in "banked" format. I hope someone here can tell you but I don't use Hi-Wave.

The file you need most which displays the menu in HyperTerm is "BootEVB-16banked.S19". Perhaps you have the same file in "linear" format that would load? The Ep9s12_mon.S19 is in linear format, but was only monitor. You need "Ep9s12_boot.s19" so I'll attach that from my Dragon12/rev-D. Make sure you still have a 4 MHz xtal. (*** sorry, I just noticed that _boot file was attached in another post *** maybe what this needs is use SRecCvt.exe to convert it to banked or linear format).

Another possible problem I dont know is if this old Hi-Wave is not compatible with your version of MCU? You can download the latest CW and try it.

Any way, the reason some programs will not load when the D-Bug12 bootloader is erased is because it was linked for the bootloader. That means the bootloader must be present to find and execute the program on powerup.

Good luck and Happy Programming!

Ah, try this to convert it to linear file "Ep9s12_boot_linear.s19" and then maybe Hi-Wave can load that.

SRecCvt.exe -o Ep9s12_boot_linear.s19 -lp -m c0000 fffff 32 Ep9s12_boot.s19

The utility can also convert same file to banked format if needed.
SRecCvt.exe -o Ep9s12_boot_banked.s19 -ob -m c0000 fffff 32 Ep9s12_boot_linear.s19

Hello there !

I would try with the DBug that came with the board. Here is mine;

(At least I think it is)

[kwik]

And here is the bootloader too ; Send the bootloader and then the DBug12;

You need to use the

fload ;b

for the boot loader and

fload

for the DBug12

because the bootloader is an s1 file ,but the DBug 12 is an S2 file
