Is Parallel jtag interface necessary

padmaashok765 — Fri, 22 Mar 2019 04:41:49 GMT

Hi,

I have used jtag for programming MC56F8367 with P&E multilink universal.

My schematic is similar to that of development board, but communication did not take place.

What will be the issue ? I have tried all the possible ideas from the forum.

I have not used parallel jtag interface. Is parallel jtag interface necessary, as most of the mc56f series boards have parallel jtag interface in there schematic.

Can anyone please help me out with this asap.

Hi, Priya,

For the MC56F83xx family, if you use CodeWarrior for DSP56800E ver8.x, you can use USBTAP, Multilink Universal device and parallel jtag interface(Wiggler).

If you use CodeWarrior for mcu ver10 or above, you can use USBTAP, Multilink Universal device..., but the Wiggler is not supported.

I suggest you use CodeWarrior for mcu ver 11 tools, if you use Codewarrior for DSP56800E ver8.x and Win10 OS together, there is issue.

You may buy the Wiggler on the market.

Hi, Thanks for your reply. I tried using Code warrior 8.3, and also 11.1 but my DSC doesnot react. I am working in Windows 7 64- bit configuration, Is there any issue with 64 bit configuration and code warrior 11.1 to communicate with target?

What else configuration settings should be given during debugging?

Hi,

I suggest you use USBTAP device or Multilink Universal device, do you use Wiggler or USBTAP device? If you use Wiggler, firstly, you have to use the PC with 25 pins parallel port, and you have to use CodeWarrior for DSP56800E ver8.3 and Win7 OS.

If you have Multilink Universal device, you have to use CodeWarrior for MCU ver11 only.

Hi,

Thanks for your reply.

I am using P&E multilink universal with codewarrior 11.1(windows 7 64bit) and i have tried the same with codewarrior 10.7(windows 7 64bit).

Is USBTAP compatible for windows 7 64bit?

Hi, Padma,

This is the configuration of CW for mcu ver11 tools for debugger. I have tried to connect CW for mcu tools with my MC56F8367EVM, I can success to connect the board with Multilink Universal device based on CW for mcu ver11.

Anyway, I suspect that your board design has issue. Because the MC56F8367 is very old, did your MC56F8367 target board work fine previously?

Hi, Padma,

I am sure that the USBTAP device is compatible with Win 7 64 bits OS.

This is the link of USBTAP device for DSC:

USB TAP for ONCE DSC | NXP

If it is convenient, you can post your schematics so that we can have a review or compare your schematics with that of MC56F8367EVM yourself.

Hi,

I tried the whole setup as such in the MC56F8367EVM schematic (using nand gates).

It worked.

Thank you Xiangjun.

Hi, Padma,

I am glad to hear that you can connect your board with Multilink Universal device, I will close the ticket.
