10:48 PM Bug #1459 (Resolved): send a flag tagging the ATR from the card
It's important to know (for the wireshark dissector or any other higher level program) if the message from the card i... laforge
10:48 PM Bug #1456 (Closed): make sure there is solder mask between pads of SAM7
The SAM7 pads currently don't have any solder mask between each other. This might lead to unwanted connections by so... laforge
10:48 PM Feature #1455 (Closed): try to improve trace width / blocking caps
If possible, we should make sure the 1.8V lines (high current / low voltage) as wide as possible. Examples are C16, ... laforge
10:48 PM Feature #1454 (Closed): add "sysmocom" text into the copper layer
We actually don't want the advertisement, but German ElektroG requires or at least strongly encourages us to have our... laforge
10:48 PM Feature #1453 (Closed): Move C21 closer to VCC_SIM pad
The blocking capacitor of VCC_SIM should be as close as possible to the SIM card socket, not some 5 cm away from it. ... laforge
10:48 PM Bug #1452 (Closed): move C14 directly to pad 4 of IC2
In v1.0p we had a problem with the blocking capacitor of the LDO being too far from the pads of the LDO. This caused... laforge
10:48 PM Feature #1451 (Closed): Atmel SAM3S to replace SAM7S
SAM3S offers 8 USB enbpoints instead of 4 for SAM7S.
This allow multiple profiles to run simultaneously (CCID and sn...

10:48 PM Bug #1450 (Closed): FTDI serial connector power supply
on P2 (DEBUG port), pin 3 is connected on +3.3V of the board.
The FTDI cable (USB to serial converter) can provide 3...

10:48 PM Bug #1449 (Closed): no solder mask between the pads of the AT91SAM7
This causes an increased risk of solder being left between the pads of the SAM7.
laforge
10:48 PM Bug #1448 (Closed): silk screen print on top of soldering pads
the way how we render the silk-screen gerber apparently puts lots of silk-screen to be printed on the solder pads.
...
laforge
10:48 PM Bug #1447 (Closed): C14 is too far from LDO, causes oscillation
The capacitor C14 is too distant from the LDO, whihc apparently causes oscillations in about a third of the devices.
...

10:48 PM Bug #1446 (Closed): test ticket to check notification
test ticket to check notification laforge
10:48 PM Feature #1445 (Closed): Some component labels (resistors/capacitors) are not readable
FB2, C3, C20, R2, C4, C23, R7, R8, R9
We should move the labels to a better location, especially not put them on t...

10:48 PM Feature #1444 (Closed): Adapt to different shottky diode footprint
The manufacturer has a different shottky diode as standard component in their SMT machine, using that diode will make... laforge
10:48 PM Feature #1443 (Closed): Adapt to different SPI flash (foot print)
The manufacturer has a different model of SPI flash among their standard components, same capacity. I will attach ty... laforge
10:48 PM Feature #1442 (Closed): Make LED footprints 0805 instead of 0603
The manufacturer has 0805 sized LEDs as standard component in their SMT machine (reel). Using 0603 will just make se... laforge
10:48 PM Feature #1441 (Closed): Use through-hole 2.5mm jack
see the description of the usb-through hole ticket: A through-hole version can deal much better with mechanical stre... laforge
10:48 PM Feature #1440 (Closed): Use through-hole mini-USB-B socket
The through-hole version would distribute mechanical stress (particularly tilt upwards) way better than teh SMT versi... laforge
10:48 PM Feature #1439 (Closed): move ERASE and TEST jumper a tint bit, so a 1x4pin header works
both jumper footprints look like a 4-pin could almost fit, but there's a fraction of a millimeter too much space resu... laforge
10:48 PM Feature #1438 (Closed): add ID-1 slot to SIMtrace
SIMtrace could also be used to sniff credit card size (ID-1) smart cards.
The ID-1 slot can be added to the back of ...

10:48 PM Bug #1437 (Closed): on resistance of bus switch not acceptable, at least not for Vcc
As can be seen from the IDTQS3244 data sheet, the ON resistance is higher tham 16 ohms in case of a 3.3V power input ... laforge
10:48 PM Feature #1436 (Closed): add VCC_PHONE to an unused GPIO
this way we can get an interrupt in software once the phone turns on VCC. laforge
10:48 PM Bug #1435 (Closed): sim card detect does not work (SW_SIM)
The SAM7 has (software-controlled) internal pull-up resistors, but no pull-down resistors.
Thus, we cannot simply ...
laforge
10:48 PM Bug #1434 (Closed): socket for FPC SIM adapter is mechanically incompatible with rebelsim fpc
while the contact spacing and other dimensions are fine, the FPC is about 1mm too wide for the socket. It can mate w... laforge
10:48 PM Feature #1433 (Closed): use 90 degree angled jumpers for ERASE and TEST
if we move the bootloader switch and JTAG further to the left of the PCB, as well as P2 further right, we create some... laforge
10:48 PM Bug #1432 (Closed): simtrace: bootloader switch without function
The problem is that there is an internal pull-up of ~ 15k and we use an external 10k pull-down, resulting in somethin... laforge
10:48 PM Bug #1431 (Closed): use PA16 for UDP_PUP as required by SAM-BA
The AT91SAM7 manual explicitly indicates in "21.6 Hardware and Software Constraints" that PA16 should be used for the... laforge
10:48 PM Feature #1430 (Closed): clearly indicate location of 'pin 1' of components and connectors
this should make it much harder to plug in the JTAG adaptor the wrong way, e.g. laforge
10:48 PM Feature #1429 (Closed): usb jack type is really hard to manually solder
For the benefit of our DIY users of the design, we should consider using a different mini-USB-B jack that doesn't hid... laforge
10:48 PM Feature #1428 (Closed): increase default trace width in simtrace pcb
the default trace width seems awfully narrow. While this may work for machine placement, manually soldering and re-w... laforge
10:48 PM Bug #1427 (Closed): simtrace BC847 footprint has B / E switched
The base and emitter seem to be switched in the BC847 footprints of the SIMtrace kicad library laforge
10:48 PM Bug #1426 (Closed): simtrace component names on silk screen unreadable
The component names of resistors and even bigger componnents are not readable as they are 'inside' the footprint of t... laforge
10:48 PM Bug #1425 (Closed): simtrace pinout of bootloader / reset switch is wrong
The pinout of the switches (buttons) in our kicad library is wrong. The way they are configured right now, they will... laforge
10:48 PM Bug #1424 (Closed): simtrace pinout of tps73633 is wrong
The pinout of the TPS73633 in our kicad component library is quite wrong. It's not a simple 1:1 mirroring, but the p... laforge
