[U-Boot] USB not working with 4.3.2 gcc compiler in u-boot 1.1.5

[Virupax SS]

Thanks 

You are correct if i use u-boot 1.3.0 with this 4.3.2 compiler, usb works 
fine.
we have done a lot of customization on u-boot 1.1.5 and it will take a lot 
of time to do those changes to the new u-boot 1.3.0. 


can u please tell me what compiler related change is done in the new 
u-boot releases so it works with the 4.3.2 GCC compiler.In which part of 
the code it is done , is it in the makefile.


When we used 4.3.2 gcc to compile the u-boot 1.1.5 , ethernet drivers were 
not working and after making some of the variables volatile , ethernet 
driver worked fine.

i made
struct  _AT91S_RxTdDescriptor
struct _AT91S_TxTdDescriptor
volatile for the macb driver , ( driver for the inbult macb in 
at91sam9260).

For the USB driver also some variable has to be volatile , but i am not 
been able to figure out which one it should be.
I have seen using the USB analyser , Data packets are not coming out of 
the USB controller correctly. 


Thanks

Your version of U-boot is about 3 years old.  Nobody will be interested 
in debugging it.  Please update to the latest and see if the problem 
exists.
