The 'two banks of flash' probably is an artifact of the same flash seen through both ESP32 cores; you can ignore it, there's only one 8MiB flash chip detected. There's two bootloaders in the ESP32, but only one of them is in flash; the one used for serial download is located in internal ROM (and is not changable or flashable as such).
If the bootloader is too large, it will clash with the partition table, so you'll need to relocate that as well; you can do that using menuconfig, Partition Table -> Offset of partition table.

Re: ESP32-PICO-V3-02
I see, thank you. But I still don't understand why after flashing via JTAG project stop flashing with UART. Probably the problem is not in bootloader size, but something else. I'm still trying to flash ESP-IDF-AT project to PICO, but the program always crushing at start. The same AT project I loaded with UART to ESP-WROOM-32D test board, and it loaded just fine:
If I load it to PICO with UART it keeps returning "invalid header" errors.
And if I load project with JTAG, it can't flash some binaries at all. There is total 17 binary files I need to flash:
0x1000 build\bootloader\bootloader.bin
0xa000 build\partition_table\partition-table.bin
0xf000 build\phy_multiple_init_data.bin
0x10000 build\ota_data_initial.bin
0x20000 build\at_customize.bin
0x21000 build\customized_partitions\ble_data.bin
0x24000 build\customized_partitions\server_cert.bin
0x26000 build\customized_partitions\server_key.bin
0x28000 build\customized_partitions\server_ca.bin
0x2a000 build\customized_partitions\client_cert.bin
0x2c000 build\customized_partitions\client_key.bin
0x2e000 build\customized_partitions\client_ca.bin
0x30000 build\customized_partitions\factory_param.bin
0x37000 build\customized_partitions\mqtt_cert.bin
0x39000 build\customized_partitions\mqtt_key.bin
0x3B000 build\customized_partitions\mqtt_ca.bin
0x100000 build\esp-at.bin
And I can't flash ble_data.bin and mqtt_key.bin. It says that there is wrong checksum or something like dat. I tried to flash them separately from other files, change their location in memory, but no use. If I just ignore them program will be still crushing after "boot: Disabling RNG early entropy source..." and return "invalid header" errors infinitely. I tried to flash those two files with UART, but PICO did not like that too.
BTW, I don't even need those files. I already have external chip that is going to use it's own LwIP library and communicate with ESP-chip with AT-commands and do all the TCP stuff, like he did with ESP8285. But I can't even disable Bluetooth, because it's required by precompiled libraries in AT-project. Well, never mind, just grumbling...

Re: ESP32-PICO-V3-02
So you have your own TCP/IP stack? Then you're using the wrong project. Try esp-hosted instead.AndreyVinogradov wrote: ↑Fri Jul 08, 2022 6:41 pmBTW, I don't even need those files.
