Hi,

I'm using LpcExpresso 7.4.0 and lpcopen_2_10_lpcxpresso_ea_devkit_4088.zip.
Inside projects that use LwIP (lwip_tcpecho_sa for example), the "data" starting address is 0x20000000 (RamPeriph32). If I run these projects, all work correctly.
If I try to set them to 0x10000000 (RamLoc64), the LwIP doesn't work.
Why?
If LwIP requires to have RamPeriph32, how is it possible to use the RamLoc64 also ?

Thanks

Hi MaxonCodeRed,
Can you let us know which board and which LPC device are you using?

Hi,

the board is our board previosly developed for ARM7 LPC2387 microprocessor and now we are testing it with LPC4078FBD100 that is a pin to pin replacement..

Thanks
