Incorrect programming of serial flash
Hi,
My configuration is: netX-50, security ROM, serial flash Atmel AT45DB321D, SDRAM Micron MT48LC8M16, USB connection
Bootwizard programs the flash and claims success.
Flash verify returns success.
However, when I read back the flash into a file: bytes 0, 1 are OK, bytes 2, 3 are zeros. And so on to the end: two good bytes, two zeros.
Bootwizard only gives me choice of 32-bit SDRAM (MT48LC2M32). That is not what I have. I have one 16-bit SDRAM chip. I suspect that this is causing bytes 2,3 of every 4-byte group to be lost.
How do I tell Bootwizard that I have a 16-bit SDRAM? I tried adding such device into netx.xml, but I still only see 2M32 in Bootwizard.
Thanks

Thank you. It works.
I previously entered the new SDRAM under netX 500 by mistake. I moved it to netX-50 and it works fine.

:D Don't worry. It is a little bit tricky. :wink:

Hi Tom,
the netx.xml file is already the right place.
You have to add a new entry as it is described in the Bootwizard manual at chapter 4.3.
