Hello,
I experience a network stack startup problem with the MCSDK udpHello example on EVMC6472. Sometimes the network stack gets stuck during startup after printing the MAC address line; when it's in this state, it does not receive any incoming packets.
I figured out that this problem can easily reproduced by loading the program (with auto-run to main), sending a packet (e.g. using ping) to the DSP and then hitting the Run button to continue. When doing this, the network stack will never come up - it always stops after outputting the MAC address, and no link message will be output. Further investigation has shown that this might be an interrupt setup problem within the EMAC driver; probably, there is a vulnerable time span in the setup during which any incoming packet causes this startup problem.
Is this a known problem of the EMAC driver? Do you have a solution? - I cannot prevent that packets are sent to the DSP even before it has finished setup.
These software versions were used:
MCSDK 1.0.0.8
NDK 2.20.2.22
SYS/BIOS 6.31.3.4.27
C64 PDK 1.0.0.06
CCS 4.2.4.00033
XDCtools 3.20.8.88
Regards,
Heiko
