Re: Problem downloading core dump from Flash

I am facing a similar situation where the coredump stores invalid (0xfffff) data on the flash (I can only see the crash reason stored as 3 | 14 on cpu0 and cpu1 which doesn't giveaway a lot about the resets happening) which seems impossible to read and mend. Does anyone have any idea how to deal wit...

Re: How to use miniz to create a compressed file that can be decompressd by gzip?

I aim to compress and store data on a file system, with the intention of later decompressing it on the cloud side. Since Miniz employs zlib-style compression, I initially assumed that I could decompress it using any standard compressor. However, I'm currently facing challenges with this aspect.

Coredump logging in RTC memory of ESP32

Hello, Is it possible to load the coredump logs into the RTC memory of the ESP32? Or maybe load the crash reason into canary byte? I know that there are attribute variables like RTC_NOINIT_ATTR/RTC_DATA_ATTR that access the RTC_SLOW_MEM (at 0x50000000) but can they log bigger strings (for example, t...
