arch/arm/src/samv7/sam_emac.c: Fixes rxdesc index logic to handle Buffer Not Available (BNA) condition. If a SOF is found, but no EOF, don't move past the frame. Instead, keep the index at the SOF buffer until the rest of the data is written. This fixes a receiver lockup condition where the peripheral and this driver get out of sync with there head pointers. In this case the driver has moved past buffers it owns, without clearing ownership, which results in the peripheral and driver in a deadlock with each other. Approved-by: GregoryN <gnutt@nuttx.org> |
