SDK example lwip_hhtpsrv_bm as XIP will not load page

[ronwal]

Hello

Using the SDK example lwip_httpsrv_bm works just fine with "plain load image" activated.

Because RAM is very limited I need to switch to XIP mode and execute my code in the external SPIFI Flash.

But when I am deselecting "plain mode image", recompile and start, the website is not loading anymore inside the browser.

Any ideas?

Logging the http comunication, shows, that the data is sent out correctly...

My setup is:

LPC54018, MCUXPRESSO V11.7.1, SDK_2.x_LPCXpresso54018 2.8.2

Thanks in advance

Ron

Hello @ronwal 

Please replace the NON_DMA_MEMORY_ARRAY definition with:

/* Memory not usable by ENET DMA. */
#define NON_DMA_MEMORY_ARRAY \
    {                        \
        {0x0U, 0xFFFFFFFFU},    \
        {                    \
            0x0U, 0x0U       \
        }                    \
    }
