From 823d9b00452b62dcee1b0692c578c6fa5eef517e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 31 Jul 2025 15:58:31 +0200 Subject: [PATCH] hw/sd/sdcard: Disable checking STBY mode in SPI SEND_CSD/CID MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The card should be in STANDBY mode to process SEND_CSD or SEND_CID, but is still in IDLE mode. Unfortunately I don't have enough time to keep debugging this issue, so disable the check for the time being and the next release, as it blocks Linux. I'll keep looking.
