PSoC Production programming using J-Link

[JaSi_1632926]

Hello,

   

I'm trying to find information on how to use SEGGER J-Link for production programming a PSoC CY8C4247 device.

   

I have found the CY8C42xx Programming Specifications document (http://www.cypress.com/file/125271/download) but it seems to be more low-level than I need.

       

Is there any documentation on how to use J-Link for erasing/flashing a PSoC?

   

The reason we won't be using the MiniProg3 is that it's not supported on Linux, which is what we use in production.

   

Or is there another, better, option?

   

Thanks, Jacob

Well, it seems like I figured it out, at least partly. Something like this seems to (almost) work:

   

JLinkExe -if SWD -device CY8C4247XXX-LXXX -speed 1000

   

connect
halt
erase
loadfile program.hex
reset
go

   

The program seems to start successfully but the loadfile step gives an error message:

   

Downloading file [program.hex]...
Comparing flash   [100%] Done.
Erasing flash     [100%] Done.
Programming flash [100%] Done.
Verifying flash   [100%] Done.
J-Link: Flash download: Flash programming performed for 1 range (131072 bytes)
J-Link: Flash download: Total time needed: 3.938s (Prepare: 0.288s, Compare: 0.103s, Erase: 0.057s, Program: 3.169s, Verify: 0.103s, Restore: 0.215s)
Writing target memory failed.

   

Again, the flashing /seems/ to work since it can start the program. But it's hard to trust this in a production setup. Anyone know why it gives an error message here?

   

Thanks, Jacob
