All uncommitted work from ESP32 GDB stub development session. Includes: - GDB stub (uos_gdbstub.c/.h/_entry.S) - Startup vector table rewrite - ESP32 HAL integration files - Boot chain design docs - AGENTS.md absolute rules (commit before refactor, no unauthorized changes) - All prior deepseek session work This commit prevents further data loss. No claims of correctness.

|
Place DAC control functions (e.g. 'dac_oneshot_output_voltage') into IRAM,
|
|
so that this function can be IRAM-safe and able to be called in the other IRAM interrupt context.
|
|
Enabling this option can improve driver performance as well.

Ensure the DAC interrupt is IRAM-Safe by allowing the interrupt handler to be

executable when the cache is disabled (e.g. SPI Flash write).

Whether to left shift the continuous data to align every bytes to 16 bits in the driver.
|
|
On ESP32, although the DAC resolution is only 8 bits,
|
|
the hardware requires 16 bits data in continuous mode.
|
|
By enabling this option, the driver will left shift 8 bits for the input data automatically.
|
|
Only disable this option when you decide to do this step by yourself.
|
|
Note that the driver will allocate a new piece of memory to save the converted data.
