Subject: [PATCH] mci: eMMC responds to CMD12 with R1 in case of read
Date: Wed, 29 Nov 2023 10:36:42 +0100 [thread overview]
Message-ID: <20231129093643.16383-1-ysionneau@kalrayinc.com> (raw)
eMMC specification JESD84-B51 states page 126
table 49 — Basic commands (class 0 and class 1) that
CMD12 (STOP_TRANSMISSION) response is R1 for read cases
and R1b for write cases.
Fix wrong reponse type in eMMC read cases.
