+# Project status and open source
+
+This repo is public because
+
+1. It has always been our intention to make this open-source.
+2. We figured it's best to err on the side of doing this early instead of late.
+3. It may prove useful to those outside our company.
+
+This is not a production design. It was designed for and served a specific 
+purpose in support of our actual production designs. It is not under active
+development, and comes with no warranty.
+
+And so, we thought it was important to explain where we're currently at, and
+manage your expectations.
+
+- We are a small company.
+
+- Our current goal is to get our first generation products finished and in
+  customers' hands.
+
+- We've created this design in support of our end-goal, not as its own thing. 
+  We're all working on the products, and tool development is a side effect.
+
+- For expediency, we've made "get-it-done" choices with libraries and parts. 
+  We may split or clean this up later, but, for now, we're primarily focused on
+  getting _our_ product ready, because, again, we need to finish our computers.
+
+- These points together mean that we may not have enough bandwidth to review and
+  integrate outside PRs right now.
+
+You're welcome to send PRs! If we have time, or if the PRs are very small or fix
+bugs, we may even integrate them in the near future. But be aware that we might
+not get to it for a while, by which time it might no longer be relevant.
+
+We've all dealt with those open source projects that feel open in name only, and
+have big patches and history-free source drops appearing from behind the walls
+of some large organization. We don't like that, and we're not going to do that.
+But please bear with us while we're scaling up.
+
+If you want to ask about whether a PR is consistent with our short-term plan
+_before_ you put in the work -- and you should! -- hit us up in an issue.
+
+Thanks!

+= SPI Mux MCN rev2-E1
+
+== Rationale
+A couple of incorrect voltages were identified though testing of the spimux.
+
+. U2 pin10 (enable) should be a 3V3 signal rather than a 1V8 signal
+. U3 pins 14 and 24 (mux select) should be a 1V8 signal rather than a 3V3 signal.
+
+Note the rework documented here will use the spare channel on the level translator so that the flash mux select goes through the level translator from the SP.
+
+To fix the first issue, we're going to disconnect R2 from 1V8 and connect to 3V3 so SP_TRANS_EN is pulled up to 3V3.
+
+To fix the second issue, we're going to run the SP signal `SP_QSPI_XTRA10` through the level translator and also disconnect
+J5 pin 1 from 3V3 and connect it to 1V8.
+
+Additionally R4 and R5 are too weak to properly drive the bus (with the level translator) when nothing is connected. these will be changed to 3.3k Ohms.
+
+== Material/Tools
+
+Aside from normal lab tools like optical magnification, solder, flux, and tweezers, you'll need:
+
+. some 30ga wire, 
+
+. qty 2 3.3k 0402 resistors (per board)
+
+. exacto knife for scraping/cutting traces.
+
+
+== Physical Rework steps
+
+To disconnect J5 pin1 from 3V3 and connect it to 1V8 do the following:
+
+. Cut the trace (`3V3`) between the silkscreen of `R2` and `R3`
+
+image::jumper_topside.png[Trace Cut]
+
+. Connect the now-disconnected size of R2 to 3V3 with a jumper wire as shown below in the 2nd picture.
+
+image::topside_jumper2.png[Jumper]
+
+. Cut the trace running along the top-side of the board `SP_QSPI_XTRA10` where indicated in red. (first picture)
+
+. Carefully expose the copper of the traces on either side of the cut to allow jumper wires to be soldered to these spots. (Light grey blocks in first picture below)
+
+. Solder a jumper (blue in first picture below) between the exposed trace and pin 12 of U2 (un-used Y8 of level translator)
+
+. Solder a jumper (orange in first picture below) between U2 pin 9 (un-used A8 of level translator) and the remaining exposed trace
+
+image::enable_level_trans.png[Level Trans]
+
+. Replace R4 and R5 on the top side of the board with 3.3k resistors.
+
+image::R4R5_replace.png[Pull-ups]
+
+. On the back side of the board, solder a jumper between J1 pin1 (`1V8`) and J5 pin 1 (see 2nd picture below)
+
+. On the back side of the board, the the trace (`1V8`) between J2 pin1 and the via, or optionally 
+carfully drill the the via to disconnect from 1V8
+
+image::bottom-side_jumper.png[Bottom Side]
+
+
+Update the board marking:
+
+- Re-label board as rev2-E1
+
+Final example rework pictures:

+
+== Determinations
+
+Until spi-mux bring-up is complete no cad changes have been initiated.

+# Model Change Notices
+We use Model Change Notices (MCNs) to track rework made in between CAD updates 
+andboard spins.
+These are preserved in this repo for historical and reference reasons even
+after the CAD has been updated.
+
+# Status
+The CAD represents what was built without the MCN(s) applied.
