Hello, I have several components in my project. Some of them are using functions from others. In order to avoid compiler to strip the functions that are not used by the main component, I use the -u option like this: main's CMakeLists.txt : <snip> target_link_options( ${COMPONENT_LIB} PUBLIC -u SpiIn...

Sorry, your link is dead.
I ran into the same issue. Please, do you have a delivery date for that?

Some more information: This morning, I went back to 3.3 with the same behaviour but, it allows me to get a stack trace: Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled. Core 0 register dump: PC : 0x4000c325 PS : 0x00060d30 A0 : 0x8008307d A1 : 0x3ffb4d80 A2 : 0x0000...

Hello, I'm running into a curious behaviour. I implemented a generic function to read a register from a external device through a spi communication: uint8_t spi_read_reg(uint8_t addr) { ESP_LOGI(TAG, "----------------read_reg at address %d -------------------------", addr); uint32_t toSend = addr & ...

Hello, With this code: tcpip_adapter_ip_info_t ip_info; tcpip_adapter_get_ip_info(TCPIP_ADAPTER_IF_STA, &ip_info); /* Create a new UDP control block */ struct udp_pcb *upcb = udp_new_ip_type(IPADDR_TYPE_V4); if (upcb != NULL) { ip4_addr_t serverIp = ip_info.gw; udp_connect(upcb, &serverIp, UDP_SERVE...

Hello, I'm building an app that sends data over udp. As a beginning, I did something like this: static void udpServerTask(void *pvParameters) { tcpip_adapter_ip_info_t ip_info; tcpip_adapter_get_ip_info(TCPIP_ADAPTER_IF_STA, &ip_info); struct udp_pcb *upcb; err_t err; upcb = udp_new_ip_type(IPADDR_T...
