Re: Assembler language reference manual ...

As for the number of cycles required for each instruction: please note that this information is not in the Instruction Set Architecture reference manual, because this behaviour is implementation-dependent. You can find an older version of the document on the Internet, just google for "xtensa isa_rm....

Re: [Q] user/custom space addr room on the SPI Flash for data

Hi @jmattsson, We've been discussing how we can implement mutable partition table, while making sure we don't accidentally corrupt it (due to sudden power off, for example). Trying to balance some requirements like bootloader complexity, reliability, and so on, we came up with the following. - In ad...

Re: Meaning of reason codes in system_event_sta_disconnected_t?

There is an anonymous enum in esp_wifi_types.h with members called WIFI_REASON_xxx. These are disconnect reasons. Will update event structure to use this enum.

Re: system_get_time() does not appear to tick until after esp_wifi_init() is called

Yes, logically it should work either after startup or after system_init. I think this function derives time from internal clock of wifi peripheral. We should change that to use either RTC or another timer.

Re: Zephyr support for ESP32

Zephyr does look good indeed, unfortunately there is no support for multiprocessor systems there right now.

Re: Recipes for saving application state to flash at run-time.

nvs_get_blob can not, in general, give you the pointer to the address space in flash, for the following reason. Flash may be encrypted, but NVS partition is non-encrypted. All memory-mapped reads from flash memory go through decryption module if flash encryption is enabled, so it is not possible to ...

Re: Video: Tutorial - Using Eclipse to build ESP32 projects

Excellent video tutorial!

I hope we can fix automatic discovery of include directories on Windows, so that manual typing of all include directories won't be required.

Re: [Answered] Maximum number of open sockets supported

I don't think menuconfig option for the number of open sockets is used anywhere. It was added as an example of potential options which can be configured using menuconfig. But it isn't used in lwiptopts header file. Setting the number of sockets by itself is not the whole story, one also needs to set...
