-### NXP S32K1XX: Debugging Tips
+### NXP S32K1XX: USB Mass Storage Programming
+
+The S32K EVB boards include an OpenSDA debugger that exposes a USB mass storage interface for easy programming. Simply copy the `.srec` file to the mounted USB drive.
+
+**Steps:**
+
+1. Connect the S32K EVB board via USB (OpenSDA port)
+2. The board will mount as a USB drive (e.g., `S32K142EVB`)
+3. Build the factory image:
 
-When debugging with GDB:
 ```sh
-arm-none-eabi-gdb
-target remote :7224
-add-symbol-file wolfboot.elf 0x0
-add-symbol-file test-app/image.elf 0xC100
-set mem inaccessible-by-default off
-monitor reset halt
-b main
-c
+make factory.srec
 ```
 
-For UART debug output, connect a USB-to-serial adapter to LPUART1 pins (PTC6=RX, PTC7=TX) and open a terminal at 115200 baud.
+4. Copy the `.srec` file to the mounted drive:
+
+```sh
+cp factory.srec /media/<user>/S32K142EVB/
+```
+
+The board will automatically program the flash and reset.
+
+### NXP S32K1XX: Test Application
+
+The S32K1xx test application (`test-app/app_s32k1xx.c`) provides a feature-rich demo application for testing wolfBoot functionality.
+
+**Features:**
+- **LED Indicators**: Green LED for firmware v1, Blue LED for firmware v2+
+- **Interactive Console**: UART-based command interface
+- **XMODEM Firmware Update**: Upload new firmware images via XMODEM protocol
+- **Partition Information**: Display boot/update partition status and versions
+- **Keystore Display**: Show public key information from the bootloader
+
+**Console Commands:**
+
+| Command | Description |
+|---------|-------------|
+| `help` or `?` | Show available commands |
+| `info` | Display system and partition information |
+| `success` | Mark current firmware as successful (wolfBoot_success) |
+| `update` | Trigger firmware update (wolfBoot_update_trigger) |
+| `reset` | Perform software reset |
+| `xmodem` | Receive firmware image via XMODEM protocol |
+
+**UART Configuration:**
+- LPUART1: PTC7 (TX), PTC6 (RX)
+- Baud rate: 115200, 8N1
+
+**Example Output:**
