[Emc-users] RPi and the endless saga of SDcard grief.

List users; I have been a RPI user since the first B version came out. I been through the "Oops the O/s is toast again" routine more than I care to count. I blame it on very poor choices for the voltage regulator and the choices of the micro USB as a power connector. Arduino scroes an A for

[Emc-users] RPI saga continues

Hi all, Too happy too soon. That is what happens. There seems to be one additional problem when configuring the SPI port. After a restart of the Pi everything went to bad again. After some digging I noticed that there might be a data-barrier problem, where peripheral register access can become

Sorry, latest news: the same happens with other 7i77. 05/29/2017 10:15 AM, Marius Alksnys rašė: Peter, can you repair or help me to repair this 7i77 board? Maybe I could diagnose more or let you connect to the system remotely. I also can replace PCB components like PIC... I issued a RMA

Peter, can you repair or help me to repair this 7i77 board? Maybe I could diagnose more or let you connect to the system remotely. I also can replace PCB components like PIC... I issued a RMA request on store.mesanet.com (never met RMA term and process before), but did not get clear answer.
