Detailed Description

src/-local shared surface for the SRAM HAL driver split.

Tag

[Ring 3 / HAL] {World: S}

Declares the module-private state shared between the two SRAM driver translation units:

• ra8_sram.c – lifecycle, ECC mode, status/clear, zero-init, self-test, introspection.
• ra8_sram_security.c – TrustZone security attribution + the ECC error callback fan-out.

The per-(global, bank) ECC error callback table lives in ra8_sram_security.c (the callback owner) and is referenced from ra8_sram.c only so ra8_sram_deinit can clear it on teardown. These extern declarations give that one cross-TU reference a single, documented home instead of a stray forward declaration.

Variable Documentation

g_sram_on_error

ra8_sram_error_fn_t g_sram_on_error

extern

Registered global ECC error callback (NULL until attach).

Defined in ra8_sram_security.c. Referenced by ra8_sram_deinit in ra8_sram.c to drop the registration on teardown.

Note

Not thread-safe; mutate under the same single-threaded context as the rest of the driver.

Warning

Do not assign directly outside the SRAM driver TUs.

Since

0.1.0

Definition at line 48 of file ra8_sram_security.c.

Referenced by ra8_sram_attach_handler(), ra8_sram_deinit(), and ra8_sram_dispatch().

g_sram_on_error_bank

ra8_sram_error_fn_t g_sram_on_error_bank[k_ra8_sram_bank_count]

Per-bank ECC error callback table (NULL until attach).

Defined in ra8_sram_security.c.

Note

Not thread-safe.

Warning
