Unable to enlarge nvs partition

For my project with ESP32 WROOM32-E 4MB (Chip is ESP32-D0WD-V3) I need a larger non volatile storage.

Currently I'm using this partioning which is working OK, all offsets are automatically calculated by the partitioning tool:

Code: Select all

# Name,   Type, SubType, Offset,   Size, Flags
nvs,      data, nvs,     0x9000,   0x5000,
otadata,  data, ota,     ,         0x2000,
app0,     app,  ota_0,   ,         0x160000,
app1,     app,  ota_1,   ,         0x160000,
phy_init, data, phy,     ,         0x1000
But as soon as I exceed the 0x5000 for the nvs partion, which in turn will offset the app0 ota_0 partition to 0x20000 (in stead of 0x10000) the ESP32 will get into a reboot loop.

So for example this table:

Code: Select all

# Name,   Type, SubType, Offset,   Size, Flags
nvs,      data, nvs,     0x9000,   0xa000,
otadata,  data, ota,     ,         0x2000,
app0,     app,  ota_0,   ,         0x160000,
app1,     app,  ota_1,   ,         0x160000,
phy_init, data, phy,     ,         0x1000
will lead to a reboot loop like this:

Code: Select all

rst:0x3 (SW_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

rst:0x3 (SW_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

etc.....

So how can I enlarge my nvs?

Help would be greatly appreciated.

Kind regards, Ronald Wijnsema

Hi,

Your partition mapping seems to be ok. I've tested here using ESP-IDF 4.4 (master) and the partition find example.

Example: https://github.com/espressif/esp-idf/tr ... ition_find

I got no reset when increasing the nvs partition.

Thank you very much for your quick reply Minatel!

I will have to investigate further then. Two possibilties seems to be remaining:
  • This is caused by me using the Arduino stack which is based on ESP-IDF 4.01 (I believe)
  • Or this is caused by the Platform I/O environment
Which one is most likely you think?

Thanks!

Hi,

Not sure about the root cause. You can test with the ESP-IDF without PIO.

Hi wijnsema,

did you flash all the new partitions to your board? Or have you tried to do a full erase of the flash? If one of the mentioned actions fixes the problem, probably something went wrong during the switch to the new partition table. But let's first see whether that's the case.

Best,
Jakob

Hi,
i think i can answer question why you cant increase size on NVS partition. Today ive been strugling with partitions problem in pio and i found something. PIO has hardcoded esptool script i think, because it is flashing app always at offset 0x10000. I mean always.
I did few experiments and here are last 2 steps that leads to that conclusion:
- STEP 1: flash test app with esp-idf and this example of partitions table:

Code: Select all

# Name,   Type, SubType, Offset,  Size, Flags
# Note: if you have increased the bootloader size, make sure to update the offsets to avoid overlap
nvs,        data, nvs,      0x9000,  0x6000,
phy_init,   data, phy,      0xf000,  0x1000,
spiffs,   data, spiffs,  , 0x30000,
factory,    app,  factory,  0x100000, 1M,
storage1,    data, fat,             , 0x40000,
storage2,    data, fat,             , 0x40000,
- STEP 2: flash with PIO and the same partition table, but with this example app:

Code: Select all

#include <Arduino.h>

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("test");
  delay(1000);
}
You can imagine how much surprised i was when i saw output log from esp-idf app instead of "test" every 1 second.

My suggestion is to put NVS partition at the end of partition table, which will fix you issue for sure.

I investigated things further and the problem occurs with the Arduino core for ESP32. It is not directly related to PlatformIO because I could reproduce the problem in the Arduino IDE, however I manually created an other partition table because the precoded tables were not suitable for me. As soon as the 0x10000 was exceeded, the ESP came in a reboot loop. It seems to be caused by PlatformIO because PIO lets you change the partitions so easy!

@chegewara is right, the partition tooling is hardcoding the first factory/ota at 0x10000. This article from 2018 is mentioning the same problem:
https://desire.giesecke.tk/index.php/20 ... n-esptool/

I played around with the solutions that were suggested in this article but couldn't get it working. Also switching to the master branch of the https://github.com/espressif/arduino-esp32/ code did not solved the problem. The 0x10000 is still hard coded in there.

When I have time I will file a bug report at the arduino-esp32 repo.

For now I am using a work-around, like @chegewara suggested, to put the nvs at the end of the table.

@ESP_jacob yes I did a full flash erase all the time before changing the partitions, just to be sure.
