Hi H-J,

As the output from JLink.exe indicates the communication with the core in general, works fine.
Could you please attach your J-Flash project to your next post, so we can check the settings?
I would also suggest to use the current release version (V4.10f) if you are using the Secure/unsecure options of J-Flash (there were some improvements in the recent time).
Nevertheless, erasing/programming the flash should also work in V4.08l without any problems.

Best regards
Alex

hi Alex,
thank you for your help.
I install the version V4.10 but when I erase the chip, I get the same message.

If I unsecure the chip, I get this massage
“Sorry, no valid license for J-Flash found.
J-Link S/N is 58001476.”

My chip is a STM32F103RBT6 (Olimex Board)

Best regards

Hi H-J,

Do you use JTAG or SWD when trying to connect to your target in J-Flash?
Which speeds (init speed and speed after init) are configured in your J-Flash project?

Best regards
Alex

Hi Alex,

first I try with Jtag speed before "Auto selection" and it was the same error. After I try with 1000kHz speed and it was the same error.

Now I change form Jtag to SWD and I errase the chip but the massage came

"sorry, no valid license for J-Flash found.

J-Link S/N is 58001476".

With SWD came in th Log window the massage "connected successfully" by SWD but how can I erase the chip??

Best regards

Hi H-J,

At this point I am not sure if I am up-to-date:

Initially you were not able to connect to your target via J-Flash.
It seems now you can connect to your target.
Is the connection problem still present or not?

To answer your question:
As indicated by the message, you need a J-Flash license to perform erase/unsecure/secure/... actions.

There are also evaluation licenses (30 days) available for J-Flash, if you want to evaluate it first.
To get such a license, please get in touch with sales@segger.com

Best regards
Alex

Hi Alex,

my problem is I get a contact with SWD but not with Jtag.

Best regards

Hi H-J,

could you please try to use a slower JTAG speed in J-Flash, when connecting via JTAG?
Please note that currently JTAG speeds up to 1/2 core speed are supported by J-Link for Cortex-M3 devices.

Since J-Link.exe is able to connect to your device via JTAG, without any problems and J-Flash also works when using SWD,
I assume a speed problem.

Best regards
Alex
