Is there any way to upgrade the firmware using just standalone SD card for QN9080 chip?
Let me check if I understand what you want to accomplish. You have a QN9080 running with an application and you want to flash another application on it? And that other application would be taken from an SD card?
Yes, That is correct, after that, I don't care about the previous application, Basically, my requirement is if I release the new firmware we are going to put into SD card and the user should be able to load the new firmware from SD card.
I don't understand exactly how you want to pass the SD card.
You can flash a new application on the board by drag'n'drop, so you can send the user the binary directly.
Also, if you want to update locally, you can update an application over the air. Take a look at the BLE Demo Applications User's Guide.pdf documentation file, section 5.19 (Over the air programming).
Regarding the SD card, if you want to update an application directly from a it, you should get a SD card module and also you need to create a bootloader which knows how to update directly from it.
Thank you so much that makes sense to me, I just wanted to know I have to
write my own bootloader or is there any way to use the bootloader from ROM
given on QN9080. I got the answer.
