Dear Support team,

When I write big data to Flash,

Flash programmer show verify error.

But, the data may be written normaly to flash.

Becase the data can be playbacked by WAB player.

Is it bug or limitaiton of size?

Sigmastudio ver is 4.2

Flash memory is w25q64fv

Best regards,

Hello Takepiro,

Sorry for the trouble.

How big is the file you are trying to write?

How many sound files are you using?

We will look into this and get back to you.

Thanks,

Dave T

Dear Dave-san,

Thank you for your reply.

File size is nearly 64M bit which is same size of Flash.

Best regards,

Hello Takepiro,

We looked at the file and the file size is actually 57Mbytes which is much larger than 64Mbit Flash size. So what will happen is that the address will overflow and wrap around corrupting the data that was previously written.

Dear Dave-san,

Thank you for your reply.

This file include text data.

The data saze is 999990 x 8 byte = 7,999,920 byte

I think it is smaller than max size of flash.

Please chack it again.

Best regards,
