FlashProgrammer fails 0x2010 bytes into a 0x4020 byte program on MPC5604B

I'm having trouble flashing the MPC5604B.

I tried this on two different chips with the same results.

It also doesn't seem to matter which location in memory is being flashed, it just fails after the Flash Programmer script tries to program 0x4020 bytes.

I tested this by creating a new MPC5604B project and using the default connection for flashing.

Here's the Flash Programmer output:

fl::target -lc "LC for Simple Flash (8)"
fl::target -b 0x40000000 0xa000
fl::target -v off -l off

It just keeps doing that

If I check the memory of the device, I can see it programmed up until 0x00005010, exactly half of the record it was trying to program.

Where is this script stored and how can I modify the behavior of Flash Programmer to get this working?

Hi,

could you:

- tell me which version of CodeWarrior do you use?

- send me the s-record file which causes the problem?

If you try to use another s-record file (just default project with endless loop, for example), is it working?

Regards,

Lukas

Hi,

I'm using CW 10.7 Build Id:160721

It doesn't seem to depend on the S-record file, I tried with other files, including the default project with this added to the top of main (to make sure the programmer had enough bytes that it would try to program 0x4020 bytes):

const int table[4096];
‍‍‍‍‍‍‍

Attached is the file from that project which fails

To be clear, the default project itself works, but the programmer doesn't program any large sections

Hi Jonah,

it seems to be a bug in the Flash Programmer – I’m able to reproduce the behavior when large s-record file is used. I will report it to CodeWarrior team.

As a workaround, I can see that it works if you use “Debug” button to program the project to MCU instead of Flash Programmer. Could you try if this works on your side?

Regards,

Lukas

Hi Lukas,

Thanks for the help!

Yes, I forgot to mention it works with the Debug option. However in this case we need to flash an s-record with a slight modification, so we will have to find a different workaround.
