ESP32 SPIFFS File name and size corrupted after code upload

[tmadushan]

Hi all,
Chip: ESP32-PICO-D4 (revision 1)
Arduino IDE : 1.8.9
esptool.py v2.6-beta1
OS : Windows 10
PCB: Custom made ESP32 module

I have a set of hex values (2348 elements) which is stored in

Code: [Select all] [Expand/Collapse]

1. uint8_t ecodebin[] = { 0x00, 0x00, ....}

I am appending each element to a file "/system/ecode" using SPIFFS. I do read after completing the writing task, and the data is read fine; not corrupted.

But, when I try to write another set of data (different file) to SPIFFS, the file I wrote earlier had corrupted. Apparently, it shows multiple files with the file name and size changed. Refer this please.

1. rst:0x1 (POWERON_RESET),boot:0x12 (SPI_FAST_FLASH_BOOT)

Ideally, there should only be one file as

Code: [Select all] [Expand/Collapse]

1. FILE: /system/ecode  SIZE: 2348

I tried different OSs, computers, Arduino versions etc. But the result is the same. FYA this actually worked perfectly fine before.

What could be the cause of this? This is a showstopper for me.
