Re: [lwip-users] MEM_ALIGNMENT value?

[Kiran Bacchewar]

hi Akshit,

 

the MEM_ALIGNMENT value once decided , you should define it in lwipopts.h file. The definations that u define in this file is reflected in the opt.h file. As opt.h file includes this file, it is in the first lines of the opt.h file... have a look...

 

about MEM_ALIGNEMENT, it depends upon the processor and also in some cases on the inbuilt Ethernet controller. Initially I selected the value 1, by the core was working fine later i found that the inbuilt Ethernet controller works fine if the alignment is 4, so i have to keep it 4. I used MPC 852 processor (32 bit, inbuilt Fast Ethernet Controller).

 

Hope this helps you,  :-)

 

Kind regards,

MEM_ALIGNMENT help says value needs to be either 4 or 2. But opt.h has default value 1. What should this be? I'm using a 32bit ARM7 processor.


Thanks
