New ContributorEPCQ remaining space read and write
Hi,
You may refer to the EPCQ flash data sheet to understand more on the memory space of a .jic file occupying the EPCQ flash: https://www.mouser.com/datasheet/2/612/cfg_cf52012-1301744.pdf
Thank you.

Super Contributora straightforward approach would be to reserve the memory amount specified for maximal uncompressed configuration file size in device handbook, rounded up to full flash sector. Use the remaining flash blocks for other purposes.
New ContributorHow can I determine how much space the .jic file has occupied in flash? Information like the start address and end address, for example.

Programming File Converter optionally generates a map file with this information.- adamShiau
Hi FvM,
In my application, the size of `.jic` file is 2MB.
I convert the `.sof` and `.elf` files into `.flash` files separately,
and then further convert them into `hw.hex` and `sw.hex` files.
Afterward, I combine these two `.hex` files into a `.jic` file.
Upon completing the conversion, I obtain a `.map` file,
with content containing information from `hw.hex` and `sw.hex` (as shown below).
My question is, if this content represents the address information in the EPCQ,
why is there such a significant difference in file sizes?
0x3BA05 corresponds to 244,229 Bytes, which is only 238.5KB.
