T3l319 Update Full [DIRECT]

The decision depends on your risk tolerance and use case:

To leverage new features, update your SDK:

Example code for the new secure storage: t3l319 update full

#include <t3l319/crypto.h>
void store_secret() 
uint8_t data[32] = 0;
t3l319_secure_region_t region = 
.start = 0x10020000,
.length = 4096,
.access = SECURE_READ_WRITE
;
t3l319_secure_wipe(®ion); // New syscall

The term “full” signals a non-reversible system repartitioning. Here is what happens under the hood:

| Component | Delta Update | T3L319 Full Update | |-----------|--------------|---------------------| | Kernel | Patched | Replaced (6.1.52 → 6.6.21-rt) | | Root filesystem | Binary diffs | SquashFS recreated | | Bootloader | Unchanged | U-Boot 2025.01 | | User data | Preserved | Factory reset (by default) | | Recovery partition | Untouched | Mirrored to new layout | The decision depends on your risk tolerance and

Because the T3L319 update full rewrites the bootloader and repartitions internal NAND flash, downgrading to older firmware is explicitly blocked after installation.

Currently, the system relies on incremental updates which can lead to data drift or orphaned records over time. The T3L319 Update Full functionality allows administrators or automated triggers to execute a complete data refresh. This guarantees absolute data integrity between the source and the destination, ensuring that any discrepancies accumulated since the last full sync are resolved.
