LPC5536 OTP-eFuse API (definition of type efuse_driver_t is missing)

[WilhelmT]

Hello,

I want to program and read the e-Fuse block of the LPC5536. For this I want to use the OTP-eFuse API. I found an example in the documentation for this.

#define ROM_API_TREE ((*uint32_t)0x1302fc00)
#define OTP_API_TREE (efuse_driver_t *)ROM_API_TREE[12]

But I am missing the definition of the data type "efuse_driver_t".

typedef struct
{
     ???
}efuse_driver_t;

Can someone tell me how or where this data type is defined?

Thanks in advance.

Hey! Hello everyone!

I'm struggling with the same issue. I need to modify the OTP-eFUSE LC_STATE value to enable read code protection, but I don't find the definition.

Can you provide further information on this? I was willing to open also a new private ticket in the project we have been opening some tickets in the last year, but my team and I are getting credential errors when attempting to open the web site.

would you mind to share your insights by here?

Thanks in advance!

BR,

Martin

typedef struct
{
uint32_t version; // should be 0x45010000 from the doc that mean v1.0
status_t (*init)(void);
status_t (*deinit)(void);
status_t (*p_efuse_read)(uint32_t addr, uint32_t *data);
status_t (*p_efuse_program)(uint32_t addr, uint32_t data);
} efuse_driver_t;
