Re: Issues running on ESP8266MOD(NODEMCU board)

I have to be honest, I totally spaced that I was supposed to be trying what you suggested. I just encountered the issue again, and was about to post another post haha. Going to try your suggestions now

[SOLVED]Issues running on ESP8266MOD(NODEMCU board)

hello all, i am having a weird issue trying to use uPython on this esp8266MOD board. after flashing the firmware to the board, the wifi activity light just constantly blinks, and when i try to open up the REPL via picocom, all i get is a bunch of garbage output that just keeps going and going. some ...

Re: W (201) cpu_start: Chip revision is higher than the one configured in menuconfig. Suggest to upgrade it.

OH! ok, i think i remember seeing somewhere now. like when compiling a custom Linux kernel, you (eventually) use `make menuconfig`.
thanks!

Re: E (523) spiram: SPI RAM enabled but initialization failed. Bailing out.

right on, thank you.
so it'll still work on devices that dont have SPIRAM, but it will throw that warning? or is that warning being caused by something else?

Re: E (523) spiram: SPI RAM enabled but initialization failed. Bailing out.

To wrap up my initial question about the warning message that pops up in the repl, when im connected to my ESP32-WROOM module: the reason that this message was shown, was because i used the firmware for the version of ESP32 that has SPIRAM (which is external?), but the version of the board that i ac...

Re: E (523) spiram: SPI RAM enabled but initialization failed. Bailing out.

i think i may have found my answer, on another post here asking that same question: "The ESP32 has a few hundred KiB of internal RAM, residing on the same die as the rest of the ESP32. For some purposes, this is insufficient, and therefore the ESP32 incorporates the ability to also use up to 4MiB of...

Re: E (523) spiram: SPI RAM enabled but initialization failed. Bailing out.

Nice! thank you for helping to clarify this. being that this breakout board has this extra SPIRAM device, this is just added to the already present : • 448 KB of ROM for booting and core functions. • 520 KB of on-chip SRAM for data and instructions. • 8 KB of SRAM in RTC, which is called RTC FAST Me...

Re: E (523) spiram: SPI RAM enabled but initialization failed. Bailing out.

AH! I get it now! I was just reading the datasheet on the ESP32 WROOM module, and was coming back here to ask for clarification on the whole "internal and external" ram stuff, and lo and behold youre already here, and have read my mind. i was reading this part in particular: `ESP32-D0WDQ6 contains t...
