TDSLite

Portable NetBurner NNDK firmware with a vendored TDSLite MSSQL client, MS-TDS PRELOGIN TLS, and a SQL web UI adapted from NetBurner_MSSQL_Client.

Primary smoke target: NANO54415.

Quick start

make PLATFORM=NANO54415
make PLATFORM=NANO54415 load DEVIP=<device-ip>

Open http://<device-ip>/ → Configure → SQL Server host/credentials → optionally enable Use TLS → Test Connection.

Remote console: http://<device-ip>/console.html

TLS

SQL Server encryption follows FreeTDS-style PRELOGIN → TDS-wrapped TLS:

1. SslInit() at boot (src/main.cpp)
2. Plain TCP connect, then PRELOGIN
3. If TLS is enabled in Configure, client advertises ENCRYPT_OFF (request); if disabled, ENCRYPT_NOT_SUP
4. When the server requires or accepts encryption (ENCRYPT_ON / ENCRYPT_REQ, or login-only ENCRYPT_OFF): TDS-wrapped wolfSSL handshake (TLS records inside PRELOGIN 0x12 packets) — not raw SSL_makeSecure
5. LOGIN7 is sent over TLS
6. If the server returned login-only encryption (ENCRYPT_OFF / 0x00), the session downgrades to cleartext after LOGINACK; full encrypt keeps TLS for queries

Peer certificate verify defaults to off for lab bring-up. See PATCHES.md and libraries/include/tdslite-net/netburner/tdsl_netimpl_netburner.hpp.
