BESS_Demo_BmsSL_SAF_V0_8_0 debug mode

starwarrior — Thu, 13 Feb 2025 05:56:57 GMT

Dear experts,

I'm currently conducting tests on the BESS_Demo_BmsSL_SAF_V0_8_0 using the RD - BESS1500BUN board. Initially, after entering the debug mode, I successfully downloaded the BESS_Demo_BmsSL_SAF_V0_8_0, and the system was functioning properly.

However, after this successful download, the board is no longer able to enter the debug mode using either of the following methods:

Press and hold SW1 (alternatively, set SW2 to the On position). Then, connect the 24 V power supply and release SW1 once the 24 V supply is connected. Ensure that D26 remains steadily lit after the process.
The FS2633 debug pin can be accessed at connector J11, pin 4. Applying a voltage ranging from 2.5 V to 6 V to this pin before connecting the board's power supply is supposed to enable the Debug mode.

I removed R228 and made an test. It turned out that the FS26 had actually entered the debug mode. However, it seems that the S32K358 has configured it to the normal mode. For instance, when I pulled down the reset pin of the S32K358, and let FS26 go to debug mode ,the FS26 won't reset. but if I release the reset pin of the S32K358, and pull it down again ,FS26 will keep reseting.

As a result, I'm unable to debug the demo any further.

Could you please advise on what steps I should take to load new firmware to the board?

Thank you!

Hi Nick,

Sorry for the inconvenience.
I sent you the latest 2024.08 version of the software via email, which should have fixed this issue.

Best Regards,
Robin
