BlueKitchen Btstack flash bank with imxrt1064

[bshannon]

Greetings,

My team is using BlueKitchen's Bluetooth API for our product. Their API offers a tlv flash bank implementation that can be used to store paired connection keys to flash. Currently, we are using NXP's fsl_romapi to write to do this, and it's working. However, we are wasting memory calling the program page function to write a connection key that is approximately 30 bytes long. So our questions are:

1. Is it possible to write to flash without writing a page at a time, if so how do we do this? (Sdk example?)
2. If we write a few bytes at a time will this have a negative impact on the flash over a period of time?

Hi @bshannon,

1. I'm afraid it is not possible to write to flash without writing one page at a time.

2. No, there is no negative impact for writing few bytes at a time.
