Hi,
I am new to the Coldfire uClinux platform. Currently I have a m5329evb board, and using the 2.6.23-uc0 kernel and 4.1.1 m68-elf-gcc. I did some stress test on the board. One interesting finding is under the ping flood (ping -f board), the kernel went to crash. I also tested the 2.6.17-uc1 kernel, the kernel did not crash but become very slow, and I measured a 24ms worst case to wake up a user process from a char driver. I am suspecting if the Ethernet driver has DMA support on m5329 uClinux. I checked both kernel, and could not find any DMA options available. Can anyone provide any insights? Thanks Xin
