Hi all, Finally i am able to build the linux tool chain from scratch. It was from the router firewall and the web safe from virgin media hub3.0 which was blocking the big size of data from espressif server. Once i disable it, i was able to build it. Hope it might help you, if you are having a troubl...

Hi all, I was trying to build the tool chain from scratch but failed to build in ubuntu 16.04 / 20.04.1.

Hi there, Can someone help me why the TX data is sending the wrong frame data. After more debugging i found very wired data coming out from the esp32 Tx. Correct data should be "021a00444e010100130022030002000032e803000302000032d0070003bced" but it sends out "0302000032d0070003bced021a00444e01010013...

We found the same issue in another board as well. At the moment we do not have log print but from the oscilloscope we can see that the yellow line is TX from ESP32 and it is sending some garbage data. I have seen in the code that there is reset for RX fifo but i don't see any reset for TX fifo in ES...

Hi there, i read some that we need to add //esp_restart_noos DPORT_SET_PERI_REG_MASK(DPORT_PERIP_RST_EN_REG, DPORT_TIMERS_RST | DPORT_SPI01_RST | DPORT_UART_RST | DPORT_UART1_RST | DPORT_UART2_RST | DPORT_UART_MEM_RST); but when i look at the SDK there is no DPORT_UART_MEM_RST Do we need to add "DPO...

By the way, Did we have any issue reported by other people regarding UART RX/TX?

Some of them are reporting in https://github.com/espressif/esp-idf/issues/2614

Could that be related.

Thanks for your response, We cannot take the scope from RX/TX as the product is in customer side. We will provide you if we have chance to capture the RX/TX line in scope.

Thanks for your help.

We have two RFID reader attached to UART1 and UART2. We have signal interference in the board. After hard reboot i see the proper communication but still we have RFID signal interference. Is RFID signal can create the problem in UART communication? Do we need any resistor or any capacitor to add bet...

We have a unit in our client side and we have unusual behaviour in UART1. After debugging remotely, i found that TX pin is not sending the data. The pin for UART1 that i am using is #define UART1_RX_PIN GPIO_NUM_22 #define UART1_TX_PIN GPIO_NUM_23 I did a soft reboot in ESP32 but did not recover. Ia...
