Can you please check - does both were same dev-id's if same, do we

[U-Boot] [UBOOT][PATCH 5/5] am43xx: add delay before xfer

[Sourav Poddar]

Without this delay, write/read is failing.
Looks like, the WIP always remain set and hence a timeout
occurs leading to the error.

Hi Jagan,
This patch seems to be necessary for read/write.
I tested by changing few timing variables, but it did not help.
The same driver works on J6 with a differnet flash(S25FL256S).
Is any one tested macronix flash at uboot?

Delay must be for macronix?
or common for all flashes.

I haven't tested macronix

Honestly, I don't recommend to use standalone delay with works for
specific to flash part.
That even harm your driver as well...
Please try to identify the fix - can you send the data-sheet link you
referred to this part...

Also please try to post the bug log w/o delay..if possible.

I will send the next version.
But, what about the delay patch, I tried other stuffs but could not see 
any thing
that helps.
So,  I will send the delay patch also as of now, to make it work out of 
mainline.

I am some how OK with that as that change is in ur driver..

Just try this change
/* FIXME: comments here... */
+#ifdef CONFIG_AM43XX
+ udelay(100);
+#endif

And also write the bug log on commit message(means with out delay)

Try to ass the testing logs on doc/ - for each time you tested a new
flash or new driver.

Jagan,

Just realised that this patches depends on AM43x base patches which are in
ti-uboot mainline tree. So, what should I do in that case. ?

Ok. Actually bassic board support is already there. But there were few
updated done on baseport side to make these reach uboot prompt. I will
test with those patches and send you only the spi part for pull bsed on
your master branch.

I am getting this error while building with this patches

I think there is something else that need to be merged from ti-uboot 
tree as I am not facing this
issue there
