2013-11-16add datasheet of SPI flash component mounted on recent boardsv1.3Harald Welte1-0/+0
At some point during v1.2p production, we switched from the S25FL016 to the S25FL032P SPI flash model. v1.3 all have that flash (so far).

If the LDO is switched off, then even if we try to forward power from the phone to the SIM, the current will sink inside the LDO (no reverse current protection).

While the SAM7 has an internal pull-up, this is of no use if the bus switch input is left open and collects noise resulting in bogus nRST interrupts.

2012-05-15SIMtrace: Improve PCB routing of GND, 3V3 and VCC tracesHarald Welte1-4148/+5879
We have to make sure the impedance of the supply lanes is not too high. Particularly bad was passing GND in 0.2mm under several resistors before even reaching the LDO from the USB socket. This attempts to address the major issues. Also, the input capacitor is moved closer to the LDO once again
