<DIV>Ken,</DIV>
<DIV> </DIV>
<DIV>The 9331 boot loader doesn't do SD over SPI for boot strap. You have
however inspired low cost alternative.<BR></DIV>
<DIV> </DIV>
<DIV>
<DIV>- Lift _CS on the existing flash.<BR></DIV></DIV>
<DIV>- Add socket jumping all signals except _CS</DIV>
<DIV>- Add switch for _CS lifting to vcc across 10K</DIV>
<DIV>- Switch to soldered flash</DIV>
<DIV>- Load U-Boot</DIV>
<DIV>- Copy flash to RAM</DIV>
<DIV>- Switch to socket flash</DIV>
<DIV>- Copy RAM to flash</DIV>
<DIV> </DIV>
<DIV>Now the whole project is $6 for a pair of sockets.</DIV>
<DIV> </DIV>
<DIV>Thanks for the inspiration!</DIV>
<DIV> </DIV>
