License: CC BY-SA 3.0 or later. If you want other angles or anything, let me know. Look at the pads in that photo, on the left and right. Those are for SOIC-16. Would it be possible to remove the SOIC-8 and solder a SOIC-16 chip on those pins?

On the X200S the flash chip is underneath the board, in a WSON package. - The pinout is very much the same as a SOIC-8, except you need to solder (there are no clips available). - images/x200/wson_soldered.jpg (image copyright (C) 2014 Steve Shenton under CC-BY-SA 4.0 - or higher, same license that this document uses) shows it wired (soldered) and - connected to a BBB. + The pinout is very much the same as a SOIC-8, except you need to solder (there are no clips available).
+ The following image shows how this is done:

In this image, a pin header was soldered onto the WSON. Another solution might be to de-solder the WSON-8 chip and put a SOIC-8 there instead. Check the list of SOIC-8 flash chips at ../hcl/gm45_remove_me.html#flashchips but do note that these are only 4MiB (32Mb) chips. The only X200 SPI chips with 8MiB capacity are SOIC-16. For 8MiB capacity in this case, the X201 SOIC-8 flash chip (Macronix 25L6445E) might work. -
Another possible solution: ground GPIO33 and boot up in non-descriptor mode. This might make software flashing possible, if it's possible to circumvent any flashing protections that might exist.
