Warm reset of eFlash by asserting reset nSRST externally or internally using SW/32K/WDOG is not supported. Only Cold reset of eFlash by powering the board ON or pressing the PBON button is supported. Asserting Warm reset results in unreliable initialization of the eFlash controller.
The default debugger connection configuration settings (Normal+Autodetect) must be used when debugging applications in eFlash. This configuration connects without asserting nSRST and enables normal debug operation. Warm reset of eFlash by pressing the nSRST button is not supported. Use the PBON button instead.
NOTE: This Caution does not affect or refer to Warm reset of QSPI or SRAM.
