Flash wear using H4P_PersistentStorage ?

Question

Flash wear using H4P_PersistentStorage ?

Closed this issue 4 years ago · 0 comments

I'm running my device all the day using H4P, and it's working good.
Until I Unplugged the device last night.

After re-power it : I get continuous reboots with Exception(28) with log & decoded stack as following :

H4 version 0.5.4

Exception (28):

What I've tested then ?

Tested Blinking LED, worked fine.
H4Plugins with WiFi , AsyncMQTT (Pangolin) : worked fine.

But this MCVE represents the error :

#include <H4Plugins.h>
H4_USE_PLUGINS(115200,20,false) // Serial baud rate, Q size, SerialCmd autostop
H4P_PersistentStorage h4ps;

void h4setup(){
    Serial.println("h4setup");
}

With log & decoded stack as following :

H4 version 0.5.4

Exception (9):

Note : It's fully working after :

Fully erasing the flash memory
Re-upload SPIFFS
Re-upload code

with the following log :

H4 version 0.5.4
H4P Version 0.5.7
h4setup

I knew this solution at the beginning.

But what could reproduce it ?
What could prevent it to happen again ?
As it would worry users in the future.

Thanks
