[lwip-users] Potential pbuf corruption at high data rate

Hi, I think this is an issue with LWIP. I have described the problem and provided the code at Xilinx Forum. The problem occurs when receiving UDP packet at high TX data rate. The issue result in wrong reference pointer to target packet ID returned by lwip_recv or netconn_recv. Ethernet NIC receive

Hello,  I am using LWIP stack (2.0.2) with pppos.I have NXP MC5748 board with SIM800c interface with one UART channel.I have used AT commands to configure GSM module.  I am trying to send data to server using LWIP socket programming. Steps of programming: 1. lwip_socket(PF_INET, SOCK_STREAM, 0);

Hi I use from 3 years Lwip and http server and it works well. I have some xml file on serwer with browser GET by js script. Now I want to add TLS to http and I use mbedTLS library. The problem is that every download of an xml file is a new http(tcp) connection and that's what the new TLS negotiatio

Dear Simon, Thank you for the response, Can you share with me the chip name for the RSA ? I have implemented the cryptography hardware accelerators on mbedtls library from ST examples, the accelerators are used in AES, DES, MD5, SHA1, SHA256 , and Entropy for the random generator. that's why the e
