Hello All!
I’m currently facing a problem:
We have purchased a license for Keil/ARM MDK which is fine for PSoC4 and 5 as long as I’m using a ULINK pro. But it does not work with a ULINK Plus, which I need for (in our case) not so rare occasions when developing smaller projects with 5V. I also found Segger J-Link Ultra not working. To me it appears that the flashloader built into µVision is doing something wrong.
Keil/ARM tell me that they need Cypress to at least assist in fixing this.
Is there a chance that Cypress will do so in the near future? It would help me very much.
Best regards,
Andreas

We do not support ULinkPlus and JLink Ultra+. We do not have such requirement from Creator and PSoC Programmer side, thus we do not do any validation w/ these probes. We only support Ulink2/UlinkPro and Jlink – refer proper sections in PSoC Creator help section.

Hello Andreas,
When you use ULink Plus/Jlink Ultra what exactly are the symptoms you are observing?

Hell Dheeraj!
The devices are erased but they cannot be programmed. Something like "Time out while flash...". Sorry, I don't have one ready at the moment.
Debugging appears to work.
The most puzzling thing is that it works with a ULinkPro.

Andreas

Did you have time to check for the error message? Please provide that information.
I didn't quite understand how debugging can work when your programming step itself is failing. Please provide the error log, it will provide us more insight on the issue.

Hello Dheeraj!
Here's the message. It's basically the same for ULINK and JLINK.
followed by
If I turn off flash downloading and use a µC that has been programmed using a different debug probe before, I can definitly debug using a ULINKplus. It appears to have reduced functionality but I can at least single step my code.
I don't know where Keil puts an error log. Can you please tell me where to find it.
Here you can see the output for ULINK:
And here for JLink:

Andreas

The error suggests that the RAM for Algorithm option in the Flash Download tab of the debugger settings might be wrong. Find more information here: ULINK: FLASH DOWNLOADING WITH CORTEX-M3 DRIVER
Can you please check the values for Start and Size based on this table below:
Please refer to the PSoC Creator help topic "Setting Up for ULink2/ULink Pro and Segger J-Link Debugger Probes" fot detailed steps on setting various debugger options correctly by using Help > PSoC Creator Help Topics in PSoC Creator.
Let me know if it works.

Hello Dheeraj!
Sorry, doesn't work. Neither for ULINKplus nor for J-Link Ultra+, same error messages as before. I'm quite sure that I tried that before.
Please keep in mind that - as stated in my original post - I already talked to Keil/ARM and they explicitly told me that they needed some sort of collaboration with Cypress to make the ULINKplus work. I think this is about FLMs.
Since I do think it private correspondence I don't want to post their answers in an open forum. So, taking the risk of violating forum etiquette, I dare to ask if there's a way of talking "in private".

Andreas
