SLM SDK Ver 2.7.0 doesn't work without external flash?

shibuta

Hi,

I have been debugging with Serial LTE Modem(SLM) without an external flash .

I made the circuit of nRF9160 (SICA) without the external flash (MX25R6435F?) , I would like to work the latest version SLM without the external flash.

I wrote the fimware with the application version(XSLMVER:'2.7.0') , but the firmware of nRF9160 didn't say "Ready", it doesn't seem to work well.

But, the fimware with the application version(XSLMVER:'2.4.0') works well without the external flash.

On debugging this, I found that SLM seems to access the external flash because the signal from nRF9160 to the external flash confirmed.

Does the SLM require the external flash? I don't know why SLM doesn't work on XSLMVER:'2.7.0'

If possible, would you tell me why to need the external flash and how to fix(avoid the external flash).

Best regards.

    By the way, I found another way to solve this problem,
    I deleted the "statement" of  the arduino_spi in a devicetree file,
    it was from 'slm/boards/nrf9160dk_nrf9160_ns_0_14_0.overlay'

    Deleted was below.

    /* Enable external flash */
/*
&arduino_spi {
  mx25r64: mx25r6435f@1 {
 status = "okay";
  };
};
*/

&uart0 {
  /delete-property/ hw-flow-control;
};Code


    And then, this problem solved (SLM begin replying) !
    I suppose the problem seems to have something with 'whether arduino_spi or not'.
    In addition this, I excepted the flash on the hardware nrf9160 side.
    How do you know anything else about the solution?

    Best regards.
