PDM_eReadDataFromRecord results in a Bus Error

[jacco_bezemer]

Hi,

I implemented PDM_eReadDataFromRecord in my JN-AN-1218-Zigbee-3-0-Light-Bulb based project. As an example i used app_power_on_counter.c.

This is my code:

typedef struct {
	uint8 u8MinDim;
	uint8 u8MaxDim;
}tsMinMaxDim;
PRIVATE tsMinMaxDim sMinMaxDim;

    	PDM_teStatus eStatus;
		uint16 u16ByteRead;
		eStatus = PDM_eReadDataFromRecord(PDM_ID_APP_MIN_MAX_DIM,
										  &sMinMaxDim,
										  sizeof(tsMinMaxDim),
										  &u16ByteRead);

Unfortunately it results in a bus error.

What am i doing wrong?

I called PDM_eReadDataFromRecord from within DriverBulb_vInit() which is before PDM_eInitialise(63) is called and that caused the Bus Error.

Now find a way to read settings from EEPROM in DriverBulb_vInit (or prior)

Hi @jacco_bezemer,

Are you sure that your identifier exists?

Please call the PDM_bDoesDataExist() in order
to determine whether a record with the specified identifier exists in the EEPROM.

Hi Mario,

Yes, the identifier exists, this is how my PDM_IDs.h looks like:

/*  application ids start from 0Xa100 */
#define PDM_ID_APP_TL_ROUTER                (0xA100)
#define PDM_ID_APP_SCENES_DATA              (0xA101)
#define PDM_ID_OTA_DATA                     (0xA102)
#define PDM_ID_APP_CLD_GP_TRANS_TABLE       (0xA103)
#define PDM_ID_APP_CLD_GP_SINK_PROXY_TABLE  (0xA104)
#define PDM_ID_APP_REPORTS                   0xA105
#define PDM_ID_POWER_ON_COUNTER              0xA106
#define PDM_ID_ZCL_ATTRIB                    0xA107
#define PDM_ID_APP_NTAG_NWK                  0xA108
#define PDM_ID_APP_CONVERT                   0xA109
#define PDM_ID_APP_NFC_NWK_NCI               0x30
#define PDM_ID_APP_NFC_ICODE                 0x31
#define PDM_ID_APP_MIN_MAX_DIM               (0xA10A)

and i tried PDM_bDoesDataExist(), but it also results in a bus error.

However this:

PDM_teStatus eStatus;
    	eStatus = PDM_eSaveRecordData(PDM_ID_APP_MIN_MAX_DIM,
    	                        &sMinMaxDim,
    	                        sizeof(tsMinMaxDim));
    	DBG_vPrintf(TRACE_DRIVER, "\nDimmer: PDM_eSaveRecordData Status = %d", eStatus);

 results in PDM_E_STATUS_OK.

So the record exists (i think).
