+SD card / SD mode / R-Car H2
+-------------------------------------------------------------------------------
+
+This is a set of example captures of SD cards in "SD mode" (not SPI mode).
+
+The cards were used in a board called "Lager" powered by a Renesas R-Car H2
+(r8a7790) SoC. The SD card was a Samsung PRO 32GB microSDHC.
+
+Details:

+
+
+Logic analyzer setup
+--------------------
+
+The logic analyzer used was a OpenBench Logic Sniffer at 50MHz.
+
+For easier measurement, the Linux driver for the SD controller was forced
+at 1 bit bus width and 25MHz max frequency.
+
+Obtained via PulseView, so no command-line.
