+FIDELIX FM25Q32
+-------------------------------------------------------------------------------
+
+This is a set of example captures of a FIDELIX FM25Q32 SPI flash chip
+(32MBit == 4Mbyte) that is read by ESP32.
+
+First part is the 2nd-stage bootloader loaded from SPI flash (using
+QuadSPI @ 10MHz). Then the 2nd-stage bootloader loads 02_blink (from SPI
+flash to SRAM) and executes it.
+
+The SPI hardware used is ESP32 DevKitC (from ESPRESSIF).
+

+Logic analyzer setup
+--------------------
+
+The logic analyzer used was a DreamSourceLab DSLogic (at 100MHz):
