Re: Burning module through flash pins

I don't think this is possible... as you stated, VDD_SIO is not available when the module is held in reset, and if the module is not held in reset, the flash pins are controlled by the ESP32. And yes, bad guys can read out your flash if they want to. That is why we have secureboot and flash encrypt...

Burning module through flash pins

Hi All, It's been a long while since I posted, but I got to a point where it became inevitable. Anyways, I wanna know, if it's possible to flash an ESP32 module (In this case WROVER) via the exposed flash pins, and flash it directly, instead of through the ESP32. This is obviously for production pur...

Flash SPIFFS partition only with Secure Boot enabled

The documentation is unclear on this, so I might ask here: I'm developing a semi-protected FW for a product. I want to use at least the Secure Boot option to protect my binary. However I'm also using the SPIFFs partition, for running JavaScript code from. The JavaScript apps will be developed by 3rd...

... but all in all it's not meant as a flagship powerhouse.
From your wording it seem that Espressif is working on a flagship power house?

Re: espressif's "Chip7 2-2-A" spotted in the wild

Well, 240MHz is well enough. Although, in this case FreeRTOS could be excluded entirely, and maybe, the chip's resources could be used more efficiently. However I still think that in more complex cases FreeRTOS or something simillar can still be a good option. One request for the devs: Please make a...

I think the I2C slave implements some kind of clock stretching now, so there's at least half a ✓ more :P

Will it be able to load and run programs from PSRAM?

Also An Interview ( 44:00 ) to Ivan of Espressif in Shanghai - ... listen to the podcast best wishes rudi ;-) Just listened to the Ivan part of the podcast. I giggled when he mentioned how difficult was the TRM. I guess here the bigger problem was that this document is english and not chinese :D Bu...

Any bets on
usb rom bootloader
Encrypted psram
Improved adc
Battery backed rtc
And possibly USB host mode? Would be nice, to hook up a LAN9415 to it :D

Re: espressif's "Chip7 2-2-A" spotted in the wild

Not quite sure looking at picture - but is the chip size 2x bigger? More cores? ) Well, in the ESP32, 75% of the chip size is the RAM :D And that is just a 2mmx2mm silicon die. So I'm guessing the bigger chip size is mostly due to it having more RAM, and more IOs. More cores and stuff can just fit ...

Re: [info] ESP-EYE DevKIT from Espressif spotted in the wild and i got one :)

Interesting, very interesting indeed. There's some information about the board here too. Most useful post. I have mine untouched so far, cause I don't know how to use it. Now I do :) The link is broken, the information is now here :) I found the correct link eventually :D I only need to know that i...
