update ncs to v2.8.0 ,can't suspend uart

[danny_zhang]

Hello,

       I  update ncs from v2.3.0 to v2.8.0 in matter windowcovering project.

        my prj.conf file:

        CONFIG_PM_DEVICE=y

        CONFIG_PM_DEVICE_RUNTIME=y

        CONFIG_USE_SEGGER_RTT=y

        CONFIG_RTT_CONSOLE=y

        CONFIG_SHELL=n

        CONFIG_OPENTHREAD_SHELL=n

        CONFIG_CONSOLE=y

        CONFIG_UART_CONSOLE=n

        CONFIG_SERIAL=y

        CONFIG_UART_INTERRUPT_DRIVEN=y

        CONFIG_UART_NRFX_UARTE_LEGACY_SHIM=n

        when I use pm_device_action_run(uart_dev, PM_DEVICE_ACTION_SUSPEND),the system interrupt conflict.

        log display:

        00> ASSERTION FAIL @ sem.c:136
        00> E: r0/a1: 0x00000004 r1/a2: 0x00000088 r2/a3: 0x20027658
        00> E: r3/a4: 0x00000004 r12/ip: 0x00000000 r14/lr: 0x00058347

        00> E: >>> ZEPHYR FATAL ERROR 4: Kernel panic on CPU 0
        00> E: Fault during interrupt handling

Hi, 

Are you using nRF54L15DK? If so, what is the hardware version on the white sticker?

Please be aware that nRF54L15 PDK v0.7.0 or earlier is Deprecated after nRF Connect SDK v2.7.0.

If you are using nRF54L15 PDK v0.8.0 and DK v0.9.1 later, please use the matter window_covering in NCS v.2.8.0 or later which provides the board config files for nRF54L15. 

Regards,
Amanda H.

Hi Amanda,

I test nRF54L15PDK(v0.8.1) and our own board,the problem is the same.Now I use the matter window _covering in NCS v2.8.0.Is there a different way to handle UART in the new version?

Regards,
Danny

NCS v2.8.0 has better support for nRF54L15PDK(v0.8.1).
