I would like to program JS16 devices.

On a 32 bit Windows 7 machine, I have no problems using the JS16_Bootloader.exe from version

On a 64 bit Windows 7 machine, I did not yet have success. I tried USBDM and 90.

The drivers are the latest and from the device manager they seem to be the same revisions on both machines.


The s19 file does not define a value for 0xFFBA (Checksumbypass), but even with this set to 00 I always end up in the bootloader, even with BLMS* tied to +5V. Before I switched to 64 bit, I did not have problems on this machine either, but at that time I was using a five years old version.

I assume that the 64 bit version somehow does not write a value to address 0xFFBA. I tried also programming via BDM, but that also did not work on the 64 bit machine, even though a verify was successful.

From an internet search, I know that somwhere there must be a thread "DB:6.94:Usbdm Cant Program Js16 At 0xffba (Checksumbypass)", but I can't find that, due to the switch from Freescale to NXP.


Any ideas?

P.S.: Programming via BDM also does not work on the 32 bit machine.
