QN9021 failed to run BLE example project

[229856331]

I run the prj_bass project, but it can not work.

I debug it with jlink, found that BLE stack APIs locate at the address around 0x01000000~0x0102000 (defined in  fw_func_addr.h), but the content of the chip in the range is all 0xFF.

SDK version 1.4.0

The marking letter of chip is  "9021    355Y5   00UMF"

I use the macro QN_9020_B4

Hi,

What is the example that you are trying to run?

What are the lib that you have included?

Please look at the next AN https://www.nxp.com/docs/en/application-note/AN12288.pdf 

Is it your custom board?

Regards,

Mario

Thanks!

The example is  QN902x_SDK_1.4.0\Projects\BLE\prj_bass.

I use the jlink commad in PRJROOT\src\link\iar\qn9020_flash.mac to get that the chip is “Device: QN9020 B3”.

After using the macro CFG_QN9020_B2, it works.

qn9020_flash.mac:

execUserReset()
{
__var chip_id;

chip_id = __readMemory32(0x40000088, "Memory");

if(chip_id == 0x2801) // QN9020 B0
{
__message "Device: QN9020 B0";
cfg_fw_9020_B0();
}
else if(chip_id == 0x2901) // QN9020 B1
{
__message "Device: QN9020 B1";
cfg_fw_9020_B1();
}
else if(chip_id == 0x2A01) // QN9020 B2
{
__message "Device: QN9020 B2";
cfg_fw_9020_B2();
}
else if(chip_id == 0x2B01) // QN9020 B3
{
__message "Device: QN9020 B3";
cfg_fw_9020_B2();
}
else if(chip_id == 0x2C01) // QN9020 B4
{
__message "Device: QN9020 B4";
cfg_fw_9020_B4();
}
else
{
__message "Error: unknown device ID: ", chip_id;
}
}
