What are differences between Espressif's TensorFlow Lite Micro and original?

TensorFlow Lite for Microcontrollers is part of the normal native TensorFlow repository. But Espressif has its own fork as well. I usually assume an ESP-specific version of a component has simplification or improvements for esp32, as compared to the creator's generic repo version. I am trying to det...

Re: Logging format in wifi component uses problematic non-standard technique

I restated the issue in a new forum post, including how to reproduce using IDF example code.

wifi component in 4.1 fails to honor log level settings

Hello, I posted about this a month ago and received zero responses. This continues to be an issue in the latest release/4.1 code. If not fixed, I will not be able to leave IDF 4.0 and move to 4.1 or 4.2. Previous post with large amount of detail: https://www.esp32.com/viewtopic.php?f=13&t=16023 (1) ...

esp-azure update has different provisioning return codes

I pulled the new updates for the esp-azure port, which now incorporates LTS_06_2020. Upon provisioning, I am seeing different message codes. Is this expected? Communication seems to work but it seems strange to change the terminology. Older version from Feb 7, 2020 usually has these codes: 2020-07-0...

Re: Does use of newlib nano format reduce stack usage?

Additional: I installed v4.1-beta2 IDF and tried to use nano and still getting same result. It will build but when azure starts running, it has the same tls error at the same point in code.

Logging format in wifi component uses problematic non-standard technique

I am sorry for reporting this so late in 4.1 development, but I just found two bothersome differences between 4.0 release and 4.1 beta2. (1) Many of the log messages coming from "wifi" component are broken into pieces, a technique not used anywhere else in the IDF as far as I can tell. (2) These Inf...

Re: Does use of newlib nano format reduce stack usage?

Well, since you have asked... I am seeing a consistent error with mbed-tls for esp-azure connection to cloud. My code has been working well before I tried compiling with newlib nano. IDF is v4.0 release. I do not have in any of my code %lld or %llx in any printf-type functions. A trick I learned on ...

Re: Does use of newlib nano format reduce stack usage?

LOL - I posted the question first, knowing it usually takes a while to get an answer. The engineers especially usually are very helpful, but sometimes takes a day or two to hear back. So, in parallel, I then did the test, which also required me to eliminate several %lld and %llx printf's in my code....

Does use of newlib nano format reduce stack usage?

I am looking for ways to reduce the amount of stack needed for tasks. It seems that even a simple task that does logging needs 3 KByte minimum of stack. I can get by without printing 64-bit integers. However, I must have logging. Will changing my config to use newlib nano format reduce the stack use...
