LPC11U67 get device ID

Pinout — Tue, 07 Dec 2021 14:30:39 GMT

Hello. How can I check LPC11U67 Device address or check its correctness? According to syscon_11u6x.h file, I'm able to get Hex value by returning DEVICEID and it is 0x002302b. But this value I get is wrong comparing it with LPC11U6x documentation. It should be 0x0000 BC88 or at least similar... Maybe you can point me in the right direction so I can get DeviceID which would match the datasheet?

Hello Pinout,

How did you read the Device ID, please use IAP/ISP Read part Identification number.

IAP command:

There is demo under LPCopen, falshiap_flashsig, you can directly refer to it.

/* Read Part Identification Number*/
command[0] = IAP_REPID_CMD; /* Read ID command code */
iap_entry(command, result);
DEBUGOUT("Part ID is: %x\r\n", result[1]);

If want to use ISP command, enter ISP mode, and using Flash Magic to read.

Alice
