Frustraded with partition table esp32C3
Hello,
I tried to ceate a partition table for my esp32 with OTA support
I need a app size of at least 1441792 bytes and also a data (littlefs) partition.
can you help me with the partition table?
1 |
# Name, Type, SubType, Offset, Size, Flags
|
2 |
nvs, data, nvs, 0x9000, 0x4000
|
3 |
otadata, data, ota, 0xd000, 0x2000
|
4 |
phy_init, data, phy, 0xf000, 0x1000
|
5 |
factory, app, factory, 0x10000, 0x144000
|
6 |
ota_0, app, ota_0, 0x160000, 0x144000
|
7 |
ota_1, app, ota_1, 0x2A8000, 0x144000
|
8 |
nvs_key, data, nvs_keys, 0x3EC000, 0x1000
|
error is
1 |
Partition ota_1 invalid: Offset 0x2a8000 is not aligned to 0x10000
|
according to the espressif forum i need
2 app partitions to perform OTA, either 2x OTA or OTA + factory.
how can i arrange this.

Thus, reducing the size of factory, ota_0, and ota_1 from 0x144000 to 0x140000 ought to be a viable solution.

4 |
phy_init, data, phy, 0xf000, 0x1000 # Offset: 0x00000F000
|
5 |
factory, app, factory, 0x10000, 0x140000 # Offset: 0x000010000

ota_0, app, ota_0, 0x140000, 0x140000 # Offset: 0x0000140000

7 |
ota_1, app, ota_1, 0x280000, 0x140000 # Offset: 0x0000280000
|
8 |
nvs_key, data, nvs_keys, 0x3C0000, 0x1000 # Offset: 0x00003C0000
|
but get this error

Error at line 2: Invalid field value 0x4000 # Offset: 0x00009000

Kinda strange.
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/partition-tables.html
One of the example tables there looks quite similar:
1 |
# ESP-IDF Partition Table
|
2 |
# Name, Type, SubType, Offset, Size, Flags
|
3 |
nvs, data, nvs, 0x9000, 0x4000,
|
4 |
otadata, data, ota, 0xd000, 0x2000,
|
5 |
phy_init, data, phy, 0xf000, 0x1000,
|
6 |
factory, app, factory, 0x10000, 1M,
|
7 |
ota_0, app, ota_0, 0x110000, 1M,
|
8 |
ota_1, app, ota_1, 0x210000, 1M,

Wait: maybe you are not allowed to add trailing comments? Try removing them.
Ah, second observation: the example table has trailing commas, as there is a possible "flags" column following the size column.
