Connecting FDT to home made eval board

Hi Guys,

 

I am trying to make a eval board for  M16/62P M30620FCPGP#U9 out of an old junk industrial product that happen  to have all the things ( micro, power supply, RS232 level shifter)  including debug port. I can read the data off the debug port when  connected to Hyperterminal (spit out by the internal program). But when I  try to connect to erase the Micro with FDT it does not communicate.I  get an error: COM5 readout error. Debug port uses UART1 and  these pins  are set as CNVSS (H), P5.0(H), P5.5(L), NMI(H),BYTE(L). What I want to  know is if this micro is locked for communication in programming mode?  The FDT is set on 115200 bauds but no communication.

 

I  am a beginer to Renesas micros so I want to know if I need to pop in a  new micro to get the board going.

 

Any help will be  greatly appreciated.

 

Thanks

Re: Connecting FDT to home made eval board

May be you should try some lower baud rate than 115200?

The FDT protocol you list suggests that communication works at 9600. The error happens only when FDT tries to switch to 115200.

Especially at higher UART speed the possible speed depends a lot on the oscillator connected to the processor.

Re: Connecting FDT to home made eval board

If you don't know the ID and all FF and all 00 don't work, then its game over.

There is no wa to erase a chip with a programmed ID (except for unsoldering the device and erase it in a parallel mode programmer, if this function is not also disabled).

Re: Connecting FDT to home made eval board

That sound pretty clear. You need a new chip - someone locked it down with a 56 bit ID key. No erase, no reprogram.

Re: Connecting FDT to home made eval board

Good news is that you can still use your board with a new chip.

 

Samples are free on-line:

If you mean the SPB, then if you're still shipping that to new users, could you please make sure it's supported under Windows 7 64-bit?  It would be bad publicity to send an eval board to someone who can't use it with a current OS, if they happen to have 7/64.

Re: Connecting FDT to home made eval board

You make a valid point.

 

However, with kits and CDs sitting on shelves in inventory we're not always able to do that.

 

There is some information on installation of the kits with Vista, and Win 7 on this website.

 

However, I think it's reasonable to sticker the boxes with instructions on what to do with Vista and Win7 (and the 64 bit versions). We'll work on that.

Re: Connecting FDT to home made eval board

This information is always included in the device manual.

R8C/M16C/M32C/R32C devices use usually UART1.

H8/SH devices use often SCI1 or SCI3.
