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 <a href="../hcl/gm45_remove_me.html#flashchips">../hcl/gm45_remove_me.html#flashchips</a> 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. - <br/> 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. </p> @@ -120,9 +118,8 @@ chip on those pins?
