- 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...
- 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...
- 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, ...
- 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...
- 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. ...
- 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...
- 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.
- 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.
... - 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
- 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...
- 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...
- 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...
- 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...
- 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...
- 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...
- 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 ...
- 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.
- 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 ... - 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...
- 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...
- 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...
- 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...
- 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.
- 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...
- 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...
- 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
- 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...
- 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...
- 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...
