We got some engineering samples of ESP32-C3 modules.
They are smaller than ESP32-WROOM and WROVER and measure just 17x13x2.5 mm!
This is the first Espressif product with RISC-V core, the datasheet is on their web.
This is also the first SOC with RISC-V core we have access to, so we are excited to learn more the ISA on low level.
Any resources to recommend? Is there something like small disassembler/monitor with few commands like read/write to memory and list code, which to allow you to write in assembly and run code?
Found this on GitHub today https://github.com/andportnoy/riscv-disassembler

Did you check out the pine64 nutcracker? It’s another riscv board, but sounds like some pretty clever people involved…

BL602 is odd choice to spread developer’s resources around unknown platform with zero community. Espressif is here for years and already proven to make good chips, backed with solid community. Why waste developer resource to unknown BL602 what does it offer more than Espressif?

That’s actually exactly what I was thinking, but nevertheless I’m expecting to see some advancement for riscv in general…

Seems that whoever these Bouffalo Lab people are, they are at least making some of the right moves straight away, like releasing documentation and making repositories available on code sharing sites. Some vendors have never come around to doing this properly or, in some cases, at all.
Espressif may be somewhat cooperative now, but I seem to remember that they were rather secretive or inaccessible to begin with, at least with the ESP8266, and that people had to work pretty hard on Free Software toolchains. Some of that “solid community” had to be built, and that work wasn’t necessary done by Espressif.
Anyway, new entrants to the business – as Espressif once were – are surely welcome. And developers can surely decide what is or isn’t a waste of their own time and effort.

RISCV is an open core, what about the wifi part?
Feb 23, 2021 @ 19:16:25
let’s wait and see, but open source wifi will never pass the regulations for sure, these things are not supposed to be modified by anyone

Well you could do it but you would have to certify every implementation, who can pay this? Who has the expertise to do so?

It seems to me that “certification” is a reasonable approximation to Open Source. As long as it is honest and not open to ambiguities and vagaries. Just making a point, as there is always a boundary beyond which only trust applies.
