Re: Access to 2 (or more) flash data partition concurrently... Some restriction?

Just to better explain my previous message: At application level I use a mutex to control/sequence accesses to each single partition. Let's suppose that two different tasks want to append at the same time some data to two different files, one of them located in LittleFS partition A and the other one...

Access to 2 (or more) flash data partition concurrently... Some restriction?

Hi everyone, I'm using an old esp-idf version 3.1.7 (I know, it is quite old but fine trimmed for my purposes...) for a commercial product. I partitioned the 8MB SPI flash of WROOM32 in order to have: 1 usual NVS partition to store parameters and 2 LittleFS partitions for various log data and config...

Re: ESP32 reboots, SPI flash issues and console baudrates...

Thank you PeterR and WiFive for your answers. @PeterR I'll try to better explain the situation. The ESP32 hardware watchdog is enabled and is linked to both CPU0 and CPU1 idle tasks and lowest priority application task. After some investigations we discovered that those reboots are caused by switchi...

Re: ESP32 reboots, SPI flash issues and console baudrates...

Hi all, I can't believe that nobody has ever faced such a situation... It is really important to understand if a wrong status of ESP32 bootstrap pins could be a possible reason for such a locked system. Moreover, just to be more explicit in my questions, is the baud rate of ESP32's console set only ...

ESP32 reboots, SPI flash issues and console baudrates...

Hi, I have a nice product using ESP-WROOM-32 in AP + STA mode. This application works mainly as expected but sometimes the system reboots and from that moment on it freezes... Looking under the hood, there is a infinite sequence of retries as shown here below: .......... ets Jun 8 2016 00:22:57 rst:...

STA connection fails in AP + STA mode

Hi, I have a product using ESP32 configured in AP + STA mode. The application running on it usually works, but sometimes ESP32 disconnects and its next connection as STA fails and starting from this moment on there is no way for reconnection to the external access point, even if the reconnection is ...

Re: ESP32 connects to Access Point but can't get IP address

Thank you WiFive and Ritesh for your precious hints... Finally I could try to debug ESP32 DHCP client behavior and discovered that there was a problem with last ARP check during DHCP sequence... This seem to be a known issue with "enterprise" access points, like Cisco Aironet Enterprise AP. Therefor...

Re: ESP32 connects to Access Point but can't get IP address

Hello,
Yes, sure, I tried with both a mobile phone and a laptop without any trouble...
I got maximum log verbosity from wifi stack but no help. Are there known issues regarding wifi chipsets incompatibile with ESP32?

ESP32 connects to Access Point but can't get IP address

Hello ESP32 forum, I'm developing an application using esp-idf_v3.1.1. ESP32 is configured in WIFI_MODE_APSTA mode, working at the same time as access point that accepts connections from WiFi clients and as station. The system usually works as expected with most access points... but... there are a f...

Re: Slowness for write operations on flash with esp-idf v3.1.5

Hi ESP_Angus,
yes, the flash erase/write operations time is pretty the same in both cases... First I should have also used at least an other method to evaluate the time intervals but I did not really expect such a FreeRTOS weakness during flash erase/write operations :-)
