Hi Sir:
Could the SUB-20 support the Flash memory functions(write,read,...)?
I am going to use the SPI Flash memory(M25P32V6G) with SUB-20 for a design test.

Yes, why not?
You can do it using SPI interface.

Hi Sir:
Thanks for your reply.
I use the SPI tab of SUB-20 tool v1.6.9 to write the Flash(25p32V) with 8 bytes data.
But the Read back data are not the same after reading data several times.
If I do not change the writing data, the read back data is always the same,right?
My connecting cables are under 15 cm of the length .
Could you advise what I should check with in detail ?
How to verify the data written into the the Flash(25p32V) with SUB-20 tool v1.6.9?
Your immediate reply is highly appreciated.

I think the best thing to do is to write your own software using the SUB-20 SPI API. The tool does not really permit the full control of the flash. BTW, when using flash, you can only write 0s over 1s to write new data in a memory cell, you must perform a flash erase before and put the data back to 0xFF.

HI,
SPI Tab is an evaluation of SPI related functions. It is not intended to burn flash like regular programmer.
There is another approach to the programmer in SUB-20 Tool:

I'm not sure it supports SPI flash currently but you can ask for it.
