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.
