Hi,

I have written some python code to use cgs.exe and ChipLoad.exe to program the 20737S on our custom board. This works well for the 20737S but after I change the Chipnames for the 20736S I get:

----------------------

Download minidriver successfully had written 251 bytes to address 0x00201000

Downloaded 0 code bytes ( 0.0%) and 0 data bytes ( 0.0%). Verified 0 code bytes ( 0.0%) and 0 data bytes ( 0.0%

).   Current state: Terminated with error

Download minidriver error trying to write 251 bytes to address 0x002010FB

Child was terminated by signal 9999

----------------------

Notice that the SDK is perfectly able to program our hardware with the 20736S on it. I'll dig into log files next but so far I would like to know whether I should have changed anything else than just the name of the chip, i.e. for btp files and directories.

Regards,

Kilian

The issue resolved itself. The reason my script didn't work was a bricked device. So my changes to my already working script were ok.

Sorry for the noise.

Hi Kilian,

Let me check following two item first.

- Have you changed everything for BCM20736S except ChipLoad.exe?

  * Is .cgs file re-built for BCM20736?

  * Is your hardware BCM20736S module?

- Can you program BCM20736S module using other environment?

  (If no, what's the difference between your boards?)

I build it for BCM920736TAG_Q32 with the SDK/Eclipse and then I use whatever l find in the associated build directory to run cgs and Chipload so I can modify the MAC for each device.

  * Is .cgs file re-built for BCM20736?

Yes

  * Is your hardware BCM20736S module?

Yes

- Can you program BCM20736S module using other environment?

Yes, I can program our custom hardware with the same firmware from the SDK

  (If no, what's the difference between your boards?)

I haven't used the Tag board for ages.

The question is does the download process differ between the devices in anything else than a few directory names in the SDK.

Kilian
