After a period of time, while working with the smartmesh python SDK, my DC2274A modules have become unresponsive. I am trying to rebuild the firmware on them using the Eterna firmware and Eterna programmer over SPI on the embedded smartmesh module. When trying to erase the flash with esp -E I received the HSP_ERR_FLASHID error message. Consulting the Serial Programmer Guide I tried esp -E -f 0. Now I get the error HSP_ERR_GETNUMDEV. What is the procedure to factory program a DC2274A module given these errors? Thanks.
