Re: esptool write_flash with encrypt option
Angus, I really appreciate your timely and well thought out responses. I will wait for the new process/documentation. FYI, all our production is done on linux machineswith scripts using esptool.py and espefuse.py. Unless there has been some change to the ESP32, I would assume that we should be able ...

Re: esptool write_flash with encrypt option
Angus, Thanks for the response. Two questions: 1. It's not clear to me how to take advantage of the "less secure" options. Is there documentation on how I would use those to go beyond the 4 flash limit? What would the process look like? 2. Is there a time frame for ESP-IDF V4.0, or even a developmen...

esptool write_flash with encrypt option
While reviewing another topic, I saw a reference to using esptool.py write_flash with an encrypt option. If I understood correctly, this allows one to get around the 4 serial flash limit when using encryption. However, I cannot find any documentation on how to use this option. For example, does the ...

Re: connection fails with repeaters
I may have solved my own problem. I suspect that the repeaters are using WEP for security, which I don't currently support.

connection fails with repeaters
I have a user that cannot connect to his home wifi. He has a router with two repeaters, all with the same ssid and password and all on channel 1. At the position where he is trying to connect, the three signal strengths are approximately -48, -73, and -78 dbm. The connection attempt is using the ssi...

Re: flash read err 100 after secure boot/encryption
WiFive, That seems counter to the script that the idf is telling me to use. In production we are using the python script that was printed out after the make. There are no delays or tests built into that script. In the example I used here, I did a "make flash". However in the production environment, ...

Re: flash read err 100 after secure boot/encryption
Angus, I appreciate the support. Do you have a timetable for modifying the bootloader? I currently don't have a way to monitor the serial output, but I'll look into it. Is there a difference in power requirements for flashing non-secure boot/ non-encrypted versus secure boot/encrypted? The flash com...

Re: flash read err 100 after secure boot/encryption
Thanks for the help. The circuit board it is on is backed up by a battery as well as powered by the USB connector. It would have to have been a local glitch of the onboard voltage regulator, but wifi wasn't running, so the power demand shouldn't have been that high. Unfortunately, this has happened ...

flash read err 100 after secure boot/encryption
I successfully flashed with secure boot and encryption six different devices. The seventh appeared to flash successfully, but then went into the flash read err, 1000 loop. I assume that this is non-recoverable. Any suggestions or ideas on what went wrong? Here's the monitor output: Dave@DESKTOP-CEOR...
