utility for programming efuses?

Hi all - Getting close to the manufacturing stage of our project. I need to write a custom MAC address and serial number into efuse block #3. I've read the docs, and I see how I can do this with a program. I'm just curious whether there exists a utility for programming the efuses directly, without t...

Re: checked out v4.1; now crashing

Hi Angus - no, I'm using the standard baud rate of 115,200. I don't think it would be a baud rate issue anyway, as I'm not seeing garbage; I'm just not seeing anything (other than what I posted).

Re: checked out v4.1; now crashing

Hi liuzhifu - I can't do that. Besides being about 12,000 lines of code, my project requires proprietary hardware to run correctly.

I've moved back to release/v4.0, where I don't get this problem.

Thanks for looking.

Re: checked out v4.1; now crashing

Monitor doesn't give me anything useful; I did it manually: $ addr2line -e build/wifibutton.elf 0x4008bb9d C:/esp-idf/components/esp32/panic.c:157 0x4008bf75 C:/esp-idf/components/esp32/panic.c:174 0x4008bf8c C:/esp-idf/components/esp32/panic.c:125 0x40099894 C:/esp-idf/components/freertos/tasks.c:2...

checked out v4.1; now crashing

Hi all - I've seen this error on occasion, but now it's doing it 100% of the time, rendering my app useless. I checked out v4.1 for any updates, and now I get this on startup: (4652) wifi: new:<1,0>, old:<1,0>, ap:<255,255>, sta:<1,0>, prof:1 I (4652) wifi: state: init -> auth (b0) ***ERROR*** A sta...

Re: "unexpected spi flash error code:101"

BTT: anyone?

Could this somehow be related to my use of the SPI RAM?

Thanks...I'm eager to get this resolved.

Re: "unexpected spi flash error code:101"

I said above I was going to open a new thread, but then I realized that the original problem is exactly what I'm facing now, so I'll continue here. This code: const char NVS_PARTITION_SYSLOG[] = "nvs_syslog"; esp_err_t Syslog::openNvs() { esp_err_t err; ESP_LOGI(TAG, "openNvs(): about to initialize ...

Re: "unexpected spi flash error code:101"

Progress report: my app is now functional (though needs more testing). I think the following changes are what made the difference: enabling the parameters CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY and CONFIG_SPIRAM_TRY_ALLOCATE_WIFI_LWIP as Angus suggested setting the option to allow malloc() to u...
