Hardfault when receiving ARP packets #170

Closed dennisvbussel closed 1 year ago

dennisvbussel commented 1 year ago

I’m trying to run a TCP Echo server. My test application is able to obtain an IP via DHCP however hardfaults before I’m able to connect to the TCP socket when handling ARP packets. Below a snapshot: image

When I build the netxduo with NX_DISABLE_ARP_AUTO_ENTRY defined. The application is (sometimes) able to connect to the TCP socket however hardfaults either on socket_accept or socket_send when eventually using ARP. image image

When I take a look at the STM32H730VBTx CPU registers the sp is at 0x2404ffc8. Which is at the very end of the RAM_D1 region (base 0x24000000 and size 320KB (0x50000)). Could this indicate a memory leak?

Toolchain STM32CubeIDE v1.12.1 ThreadX & NetXDuo v6.2.0_rel STM32H730VBTx (Code execution from external flash in XIP mode) DP83825I driver (own implementation forked from the lan8742 driver provided by ST)

Never mind.... Enabled the stack checker and the App TCP Thread stack seems to cause issues, after doubling it the issue seems to be resolved.

Good to know your issue is resolved.
