Re: What would you like to see in The Next Chip?

1. Fix I2C controller, transaction continuations in particular: ACK clocking should not be delayed until next batch of data and also the controller should, like, stop going haywire from time to time. currently I2C controller is unusable because of this. https://github.com/espressif/esp-idf/issues/60...

Re: MQTT Broker on ESP32

yes, everything has been checked in. ESP32 port is more or less complete, except JS (major rework here, for all archs) and OTA (coming in the next few weeks). i will then work on ESP32-specific stuff such as secure boot (very much interested in this myself)/ right now, check out the tuturials: https...

Re: MQTT Broker on ESP32

Mongoose MQTT broker and client already works, including one-click (ok, one CLI-command) AWS IoT onboarding, with optional ATECC508A crypto-chip support.

basically, if you want MQTT and/or AWS IoT, Mongoose is the way to go.

Re: Proper way to init phy_init and NVS?

ah, so there is an option to generate PHY data. i'll use it then.

i want "miot flash" to bring device to a known clean slate, so i think i'll erase NVS just to be sure.

thank you, gentlemen!

Proper way to init phy_init and NVS?

ESP8266 used to ship a small init file for sys params area.
i see that esp-idf does not flash anything to these areas, but i'd like to initialize them to known state.
is it ok to just erase the area (i.e. fill with 0xff)?

Re: ROM functions

thank you, that makes sense. one suggestion from me: please implement stronger checksums during flashing than a simple 8-bit xor! crc32, adler32 (weaker but very small code), or just use md5/sha1/sha256 if you intend to have them included anyway. i have implemented a better and faster flasher for 82...

Re: Flash Tool

i can confirm that GPIO0 to GND is all you need. withthe console output you posted, it looks like you get into bootloader fine.
can you post the error you get?

Re: ESP32 Free Heap

I am not entirely sure. Could be that the 48K is used by the ROM. ok, i actually miscalculated and it's 32K. but still, it is a big chunk of heap unaccounted for, would be nice to have it back or at least know that it's intentional. can you clarify it? you could possibly use this by just pointing a...

ROM functions

is this really all there is?
for example, have all crypto functions been removed from ROM?
i suspect not. can you please publish the list of exports and (important!) C decls / prototypes for them?
full documentation would be nice too, but headers or even just addresses would be a good start.
