Issues with External SPI Flash
I have a custom design PCBA that mimics the beacon reference design (exact same circuit). For reference, I am running from a primary lithium cell and bucking. However, I am using AT25XE011 as my external flash. The FW I am running is your DA14580_BEACON_3.40.6-> dialog_beacon_fh. The beacon does function, can boot from flash (and SmartSnippets can connect and erase/write/read external flash thru JTAG), and advertises.
