hci_lpuart - v290 - 91x - RAM overflowed

Simon

Hello,

hci_lpuart builds fine in VS v290 with thingy91/nrf52840.

If trying with thingy91x/nrf5340/cpuapp/ns,
build is going ok until the very end when RAM overflowed message stops the build,

region `RAM' overflowed by 267184 bytes
collect2: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.

This case mentions Case ID's of ongoing hci_lpuart issues, maybe its 91x:
339543
338886
(not sure how to search for Case ID, in search box or by URL string)
The docs for hci_lpuart mentions thingy91, maybe ok for 91x too.

thank-you,

    Hello, 

    The docs for hci_lpuart mentions thingy91, maybe ok for 91x too.

    Yes, it should work for the Thingy:91x as well.

    If trying with thingy91x/nrf5340/cpuapp/ns,
    build is going ok until the very end when RAM overflowed message stops the build,

    I also see this issue, but building for thingy91x/nrf5340/cpuapp does not give this issue. You should be able to use this build for the nRF5340 on the Thingy:91x. Did you try this? I did not test on my side unfortunately.

    This case mentions Case ID's of ongoing hci_lpuart issues, maybe its 91x:

    The cases that are mentioned in this ticket are private tickets from the same customer. 

    Kind regards,

    I did try thingy91x/nrf5340/cpuapp, but this would have led to my next case.
    Was looking at keeping these two issues separate.
    Once the non ns hci_lpuart sysbuild is compiled and in the process of being flashed from VS,
    nrfutil not found error comes up,

    -- west flash: using runner nrfutil
-- runners.nrfutil: mass erase requested
-- runners.nrfutil: reset after flashing requested
FATAL ERROR: required program nrfutil not found; install it or add its location to PATH

    Tried flashing 91x on VS Win11 and Ubuntu 24.04.2 LTS and same nrfutil result.
    If you then try to flash nrf9160-dk or thingy:91 on VS, no issues with nrfutil and flashing is normal.
    Tried also with blinky, wifi_scan, lte_ble_gateway sysbuild for 91x and all end up with nrfutil not found.

    thank-you,

    Have you installed nrfutil on your computer? nrfjprog is officially deprecated and is being replaced by nRF Util.

    Please download and retry.

    Now when trying to flash non ns thingy91x/nrf5340/cpuapp sysbuild on VS v290 and switch set to nrf53,

    -- west flash: using runner nrfutil
-- runners.nrfutil: mass erase requested
-- runners.nrfutil: reset after flashing requested
-- runners.nrfutil: Flashing file: /home/simon/ncs_apps/hci_lpuart-91x-v290/build_3a/merged_CPUNET.hex
-- runners.nrfutil: Erasing flash and UICR
-- runners.nrfutil: Programming image
Error: One or more batch tasks failed:

    Gave a try using v3.0.0-preview1 thingy91x/nrf5340/cpuapp/ns, and same ram overflowed.

    Hello,

    I see from the board files, particularly the file:

    NCS v2.9.0\nrf\boards\nordic\thingy91x\board.cmake

    Line 8-12 should be:

    elseif(CONFIG_BOARD_THINGY91X_NRF5340_CPUAPP OR CONFIG_BOARD_THINGY91X_NRF5340_CPUAPP_NS)
  board_runner_args(nrfjprog)
  board_runner_args(nrfutil "--nrf-family=NRF53")
  board_runner_args(jlink "--device=nrf5340_xxaa_app" "--speed=4000")
elseif(CONFIG_BOARD_THINGY91X_NRF5340_CPUNET)

    Note that there are two corrections on line 8. 

    Try this, and see if it helps.

    Best regards,

    Edvin
