AWR2944: The difference between xWR294x ES1.0 and xWR294x ES2.0

Hello Rata,

What you using from the revision of the EVM looks like the ES 1.0 device.
ES 1.0 vs ES 2.0 is a silicon revision.
The demo you are trying to run is for ES 2.0, so it will not function at all.
Can you please read this register and let me know the value of the register: 0x030E0430 so we can confirm which silicon you have?

Regards,
Saswat Kumar

Hi Saswat,

  The  value of the register  0x030E0430  is 0x400001.If my version is ES1.0, does is it mean that I can not use the demo in the radar_toolbox_1_20_00_11?If I want to use that, I must change the AWR2944 EVM to ES2.0, that is to say that I have to buy another AWR2944 EVM ,is that right?

BR,

Rata

Hi Saswat,

     Thanks for your reply. Now I have another question,in the linker file r5f_linker.cmd

   GROUP {
        .lwip_pools:  (NOLOAD)
        {
            . = align(128);
            *(*memp_memory_POOL_1792_base*)
            . = align(128);
            *(*memp_memory_POOL_4096_base*)
            . = align(128);
            *(*memp_memory_POOL_128_base*)
            . = align(128);
            *(*memp_memory_PBUF_POOL_base*)
        } palign(128)
    } > DSS_L3

When I build the project, the lwip_pools size is 0xe0100,about 1M mempry. Now I want to reduce the size, I do like this:

I change the content of the header file 'lwippools.h'  to

#if MEM_USE_POOLS
LWIP_MALLOC_MEMPOOL_START
LWIP_MALLOC_MEMPOOL(80, 128)
LWIP_MALLOC_MEMPOOL(100, 1792)
LWIP_MALLOC_MEMPOOL(4, 4096)
LWIP_MALLOC_MEMPOOL_END
#endif /* MEM_USE_POOLS */

the previous content is

#if MEM_USE_POOLS
LWIP_MALLOC_MEMPOOL_START
LWIP_MALLOC_MEMPOOL(100, 128)
LWIP_MALLOC_MEMPOOL(320, 1792)
LWIP_MALLOC_MEMPOOL(4, 4096)
LWIP_MALLOC_MEMPOOL_END
#endif /* MEM_USE_POOLS */

By that, the lwip_pools size is reduced to 0x7d500, I don't know whether  it has a bad effect. At the same time，I want to know the function about the above configuration.

BR,
