Need Help on UnSecure MCU

[Kennybug]

TBDML hooked up.
P&E startup is alright.
But the P&E unsecure cmd just not work.

I have tried several osc speed.
only 40MHz talks for my board.

My TBDML had a 12MHz osc.

12 and 16 does not work at all. any clue?

[Kennybug]

here is part of the log.

Very funny that the log said the unsecure cmd correctly executed.
but the window pop out said the bit was secured.

Code: Select all

Kennybug:

See https://github.com/DeuceEFI/FreeEMS_Workstation_Setup for how to unsecure the MCU...
hint: see Chapter 1, Step 3 and Step 6 (pages 3 and 4 of the .pdf file)

Hope that helps

[Fred]

Weird, how did that happen? I didn't have to unsecure mine loading from Linux.

[Kennybug]

Andy,
basically, i had followed you procedure from the pdf file.
hiwave works and the P&E cmd are running.
but it just pop out an error message as my screen capture.

a few questions:
1. what speed you are using in hiwave?
2. do your have the "not connect secured"on the status bar?
3. do i need to put the load/run jumper closed?


Fred,
My debian cannot regonize my TBDML, will try later tomrrow.

[Fred]

Can you get hold of, or build the USBDM unit? That's what I have and it works great.

[DeuceEFI]

I will look at my Hiwave configuration when I get home in a couple of hours, but I think this may tell us there might be a problem with the driver or with the MCU configuration file:

==> C:\Program Files\Freescale\CWS12v5.1\Prog\gdi\tbdml_gdi12.dll
GDI: DiGdiOpen()==> DI_OK
GDI: DiGdiVersion()==> DI_ERR_NOTSUPPORTED

I'll post again once I verify the operation of my TBDML at home...

p.s. I have had better luck with my USBDM as well

[Kennybug]

It's likely my MCU not sync the bus speed with the TBDML.
I have to manual set the speed, otherwise the MCU not found.
I guess the capactor c10, c11 values do matter.
i may need other capacitance for my TXC crystal

another thought, may be my TBDML firmware cannot use CWv5.1, will downgrade to V4.7 and retry tonight.

[Fred]

What about cw 10.x ?

What is TXC ?

[Kennybug]

Fred,
TXC is the brand of the crystal i use, I bought them from element14.
I am now using 22pf per Andy's BOM. however, the crystal suggested 18pf.
The load capacitance is definately wrong on my board. osc amplitude may be too weak.
I think that is the reason why sometime Hiwave set cannot find MCU.

My TBDML labeled it is v1.3, and hiwave regonized it had v0.9?? firmware.
While i bought this toy, The seller emailed a link for download the CW4.7.
So i will try CW4.7 1st.

I may going ahead to buy latest version USBDM from china.
