Partition table error

[c32958]

Hi,

I've assembled my first prototype ESP32 PCB and cannot get my code to boot up. I have a ESP32D0WDQ5 installed and I am able to successfully flash my code with an FTDI serial cable:

I cannot get past a bootloader partition error:

Code: Select all

I've already moved the partition table up from 0x8000 to 0x10000 (I'm not using encryption yet, but I figured the debugging from the bootloader might increase the size and step on it). I've also read the partition table back using:

Code: Select all

python /home/c32958/esp/esp-idf/components/partition_table/parttool.py --partition-table-offset 0x10000 get_partition_info --table ppp

and dumped it with

Code: Select all

python /home/c32958/esp/esp-idf/components/partition_table/gen_esp32part.py ppp

and it comes out exactly as it should from my partitions.csv file:

Code: Select all

# Espressif ESP32 Partition Table
# Name, Type, SubType, Offset, Size, Flags
nvs,data,nvs,0x12000,16K,
otadata,data,ota,0x16000,8K,
phy_init,data,phy,0x18000,4K,
ota_0,app,ota_0,0x20000,1500K,
ota_1,app,ota_1,0x1a0000,1500K,

So I don't think that I have a problem with the flashing. I've also read back the actual ota_0 partition and compared the first few hundred bytes and they are exactly as they should be from the binary file for the executable.

I would welcome any ideas or pointers on how to diagnose this.
