Hi All,
In file post/memeory.c the following comment is there
/*
* This is 64 bit wide test patterns. Note that they reside in ROM
* (which presumably works) and the tests write them to RAM which may
* not work.
*
* The "otherpattern" is written to drive the data bus to values other
* than the test pattern. This is for detecting floating bus lines.
*
*/
This comment gives an hint that this code is specifically for the 64 bit
wide SDRAM only.
I ran the same code on the ep8248 board in which the port size of the RAM is
32 bits it worked there, didn't throw any error.
I just want to make it sure that, if the port size of the RAM is 32 bits
will this test work with out any modifications or do I have to make some
changes.
Regards,
Vikrant
