Step:

1. Download CySuiteUSB and install it, locallly cache copy Media:CySuiteUSB_3_4_7_B204.zip
2. Edit the "\Cypress\Cypress Suite USB 3.4.6\Driver\bin\wxp\x64\cyusb.inf" file - uncomment and edit the device id's into the proper section:

• e.g. for 64bit windows 7:
• [Device.NTamd64]

Build ( Version 1 )

• Step 1. Add the Cypress chip.

add the cypress chip, orientate, align pads, tag one pin on one corner, recheck alignment, tag opposite diagonal corner, recheck alignment, fix if moved, once its square tag other 2 corners then lay a line of thing solder paste across the pins and solder one leg at a time.
Lots of flux. Use a line of very thin paste over the pins, close to the bend, then put the iron between the legs and hold it for about 3/4" of a second, give the chip some time to cool down, so do 4 sets of pins, let it cool, then another four.
The larger blobs of solder are partially because of the camera, i use the ground plane to remove excess solder from the tip of my iron as i work, this helps to reduce bridging. Obviously this only works when there is no solder mask, use a scrap piece of copper or a sponge instead.

Debugging the Design

Later versions of the software stopped working with most of the designs out there. Initially we looked at the I2C/SPI EEPROM contents by attaching it to a breakout board and reading it. After tracking down the chip type ( knowing its an small i2c/spi EEPROM with a SOT-23-6 package).

So after plugging it into a chip reader and checking the results. It showed the chip repeated the VID/PID plus some extra data, after changing the chip type that wasn't the issue.

Then we looked at the _RESET line. USB wants the reset to be at least 5ms but no longer than 500ms. I used a 10uF capacitor, so we dropped that down to 1uF but left the resistor alone, that didn't change things other than make the USB more flakey on hub's and other PC's ( propagation delays).

Most chip manufacturers have reference data sheets ( See Link #1 below ) and a schematic design rule check. It specifies 12pF each for XTAL starting caps, and not to use any resistors at all on the USB. So those are the changes we'll make next. I'm leaning towards it being a chip reset/boot time problem.
The resistors probably aren't causing this, but we'll change them out anyway and look at the results

Next step is to change the resistor/cap on the reset line and look at the reset line with a logic analyser, yes we're using the same device to debug itself !

After some pondering, another issue might be that the discharge time on the capacitor on the _RESET line, when power off ocurrs ( possibly during the firmware upload) the cap will slowly discharge, if the discharge time isn't faster than the time for the power to cycle ( has to to drop below logic 1 voltage) there will be no reset. Adding a diode across the resistor will cause the cap to discharge very quickly



We removed the whole reset circuitry from the original, no difference. So next step is to swap the cypress chip with a new one.
With a logic analyser we determined the problem!
