Description
Describe the problem
I use NVS to my project a lot and used a custom partition just for the sketch and the nvs.
factory,app,factory,0x10000,0x140000,
nvs,data,nvs,0x150000,0x2B0000,
Even tough i maxed out the nvs i still get crashes when i try to save data to nvs. the data i try to save are long strings split into chunks due to the limitation size per key but with no result. it keeps crashing when it comes to saving.
02:19:07.427 -> abort() was called at PC 0x400849b3 on core 1
02:19:07.427 -> Backtrace: 0x40082900:0x3ffc097c |<-CORRUPTED

Using an addon exception decoder from the 1.8 version ide did not help me as well

0x40082900: panic_abort at /home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/esp_system/panic.c line 469
I save many types of smaller variables to nvs but even with smalled chunks it cannot be handled
To reproduce
======================To write data======================
const size_t chunkSize = 1900; int totalChunks = (DataLog.length() + chunkSize - 1) / chunkSize; preferences.begin("my-app", false); preferences.putInt("DataLog_chunks", totalChunks); // Store how many parts for (int i = 0; i < totalChunks; i++) { String chunk = DataLog.substring(i * chunkSize, (i + 1) * chunkSize); String key = "DataLog_" + String(i); preferences.putString(key.c_str(), chunk); } preferences.end(); Serial.println("DONE");
====================To read data=============================
preferences.begin("my-app", true); // true = read-only mode int totalChunks = preferences.getInt("DataLog_chunks", 0); if (totalChunks == 0) { Serial.println("No chunks found. Using default DataLog."); DataLog = "looooooooooooooong string..... about 1kb "; // Optional fallback } else { DataLog = ""; // Clear previous content for (int i = 0; i < totalChunks; i++) { String key = "DataLog_" + String(i); String chunk = preferences.getString(key.c_str(), ""); DataLog += chunk; } } preferences.end();
Expected behavior
Expected to save the data with no issue. Also how to handle panic events? to be able to halt or not on crash?
