PSoC4 - CY8C4014LQI : Writing to metadata user-data section through bootloadable

[MehulK]

Hello,

I have two separate projects, bootloader and boot loadable application on CY8C4014LQI-422. I am looking to write a non-volatile byte of data, which can be updated by the boot loadable.
Since the device doesn't have an EEPROM, I am trying to write a byte of data into the metadata user data section through bootloadable.

There is a function---   void Bootloadable_SetFlashByte(uint32 address, uint8 runType) ; which could have been used to perform the write operation. However, in v1.60 this piece of code is obsolete. 

Is there some other way by which the data could be written?

Thanks!

Hi

I have attached a project where you can store 2 bytes in the checksum exclude region.

For that you need to set the checksum exclude section as 1 row = 256 bytes(depends on device used)

Please let us know if the attached project helps to solve your query.

Thanks for your response.. 

in this project, data is being written through the bootloader and read through the bootloadable..
I am looking for a way to write and read through bootloadable.

Thanks.
