Well, the result is ambiguous: Without that 'broken' flag: mmc works poorly, but becomes more or less stable when MMC clock downs to 6MHz (90% boots without errors). On the 12MHz MMC clock the issue doesn't appear in 50-70% cases. On the 24MHz MMC clock the device never boots up. However with the flag: MMC works stable on 24MHz MMC clock (boot issue observed only once), but if I increase MMC clock speed even a bit the problem appears oftenly ( >70% of cases). So, that flag definitely helps a lot, but the nature of the problem might be different. BR, Siarhei
