device crashing at sd_softdevice_enable

I'm trying a new device based upon the nrf52810 and it won't run past sd_softdevice_enable - it goes to the assembler window and halts. The device does have a 32kHz xtal and i've tried all those remedies to no avail. The device is a Taiyo Yuden EBSLSN dev kit.  TY_BLE_EYSLSN_EVBManual_V1_0_20190227.pdf

  • I'm using the nRF53811 with only 196K of flash and am using the HIDS keyboard example. To get beyond this error I needed to disable a bunch of stuff like the UART driver, power manager, scheduler, sensor simulator, buttons & LEDs, turn the debug level down, disable all the RTT logs, and more. I would recommend that nobody use the 52811 or 52810 devices if you're going to be using a softdevice and any functionality beyond that in a basic example. Also had to change a bunch of compiler directives, one notable one being the NRF_SD_BLE_API_VERSION=7, which needed to be removed.
