#include <nitro/ctrdg.h>
void CTRDG_WriteAndVerifyAgbFlashAsync(u16 sec_num, u8* src, u32 verifysize, CTRDG_TASK_FUNC callback);
| sec_num | The destination flash sector number. |
| src | Writes the source address. |
| verifysize | The verify size in bytes. |
| callback | The callback function called when WriteAndVerify processing ends |
None.
This function internally uses CTRDG_WriteAgbFlashSector and asynchronously writes data and then CTRDG_VerifyAgbFlash asynchronously verifies data for the number of bytes given by verifysize. If there is an error, the function retries up to the number of times specified by CTRDB_AGB_FLASH_RETRY_MAX (defined in AgbFlash.h). You can find out whether the WriteAndVerify process succeeded by accessing the result member of the CTRDGTaskInfo structure used as an argument to the callback function that returns after this routine is called. It is 0 if the WriteAndVerify process succeeded, non-zero if the process failed, and the error address on the device side if there was a verification error. Note: When checking error codes, this function returns an error code using 16 out of 32 bits when there is a write error, but returns a 32-bit error address on the device side when there is a verification error.
The access cycle setting does not need to be set beforehand because it is created inside the function. In addition, the OS_InitTick function must be called before this function because clock ticks are used by this function to measure timeouts.
Note: All interrupts are disabled inside this function and the cartridge bus is locked for a set period. In particular, when this function is called, do not use DMA that starts automatically during direct sound and V/H blank synchronization, display synchronization, cartridge request, etc.
Note that the AGB backup device cannot be accessed normally with version IS-NITRO-DEBUGGER 1.66 or earlier.
