efiwrapper sdhci error during fastboot flash

[base2]

How can I get more debug information about an error that occurs while doing a fastboot flash command on an Apollo Lake platform? I've seen two errors, but can't find supporting documentation. Here are the errors:

efiwrapper: err_sts 20 auto_cmd12 0

efiwrapper: sdhci_wait_cmd_done() CMD23 Error Int asserted 1
