Re: Document Requests

If I want to port the esptool.py to another language, is there a document somewhere specifying the protocol used to communicate with the ROM bootloader? Or do I have to infer it from the python source? I will do the latter if the former isn't available, but having documentation would speed up the p...

Re: Selecting spi_flash_mmap address

As an addendum to the above (which is 100% correct), please consider using esp_partition_mmap() whereever possible. It doesn't have the 64KB alignment requirement, and it allows you to use partition-local offsets which are simpler in most cases.

Re: ota checksum failed

I've seen this kind of problem with faulty or browning out flash. Can you please share some details about the exact hardware configuration you have? (ie Espressif or other branded module, or bare chip on a custom board, what flash voltage, etc.) If you still have physical access, one thing you can d...

Re: What's the matter with the esp32 D2WD Flash download fail ?

ESP32-D2WD can not download,the situation I've met too recently. You have quite an old version of esptool.py (v2.0beta1, it's printed in the log output). This version pre-dates ESP32-D2WD support. Please get a newer esptool.py or newer ESP-IDF (which includes esptool.py). esptool.py v2.0 final or n...

Re: Can I ask where is introduction section

Hi John,

There's a link to the Terms of Use at the bottom of each page: ucp.php?mode=terms

(I think it's also linked from signup.)

Do you have some particular questions about using the forum? We'd be happy to answer them.

Re: Getting "W (416235) wifi: ampdu, m eb failed" error while receiving packets

@ESP_Angus Hi, Angus, I used the latest commit 9b30f66 for my project. I create a TCP server using netconn, and then got the issue. But when I use lwip socket API to establish connection with client, it seems no problem. Is there anything wrong with netconn lib? It's possible, most of our testing i...

Re: Flash Encryption Disable

Hi Rahul, There are some unusual things in the efuse summary: CONSOLE_DEBUG_DISABLE, JTAG_DISABLE, DISABLE_DL_ENCRYPT, DISABLE_DL_DECRYPT have all been burned (set). Normally these are automaticlly burned by the bootloader after it successfully finishes the first encryption pass and enables the flas...
