    The software, that runs on the picocomA5 is an echoserver. That means it reads on port 7 udp and resends the data. The other side generates some well known data, sends this data to the picocomA5 and verifies the content. If successfull it prints out the time difference between sending and receiving. This is done in a loop from 10 to 65000 with an increment step of 16. That means the first udp packet has the size 10, the next one 26, etc. The bug ERR6358 could be observed 1 to 10 times for one co…

    There's a bug in sgtl5000.c concerning PCM Playback Volume. The TLV entry is missign. This patch addes the TLV entry.

    NXP decribes in VYBRID_2N02G.pdf a bug in the ethernet controller of the processors imx6 and VF500. This bug in the errata sheet is ERR6358. The effect is, that some of the ethernetpackets will not be send, or send with a big delay. In fact it is never the first packet, of a bunch of packets, that will be delayed. In our case, the delay could be 4 seconds or more. Newer versions of the ethernet driver fec.c have a correction for that problem. I This is the patch Index: drivers/net/fec.c ========…
