I am evaluating BCM943341WCD1_3 to act as a LAN to WLAN bridge. I find that bus_data_credit gets frozen after millions of packets sent out to wireless side. As it is frozen, future sendings will fail as wwd_sdpcm_get_available_credits() returns 0 always.I check the last batch of packets just before bus_data_credit gets frozen and find they are perfect. I review the SDK code with no hints. Maybe the experts from Cypress can check the source code of the firmware: 43341B0.bin to figure out the possible reasons.
