====== Convert eMMC to pSLC ======

To ease converting the userspace of the eMMC to pSLC, TQ Systems has extended the functionality of U-Boot.\\

**Please Note:**\\
The following instructions have been tested on the\\
  * TQMa6x BSP REV.113
  * TQMa7x BSP REV.105
  * TQMa6ULx BSP REV.104
  * TQMLS102xA BSP REV.109

** The hardware partitioning of the eMMC is a one-time, non-reversible action.A  all data on the eMMC gets lost when converting.**

  * Set Starterkit to boot from eMMC please see the appropriate wiki page how to set the DIP switches:\\  [[https://support.tq-group.com/doku.php?id=en:arm:tqma6x:mba6x:dip_switches|TQMa6x]] \\  [[https://support.tq-group.com/doku.php?id=en:arm:tqma7x:mba7x:dip_switches|TQMa7x]] \\ [[https://support.tq-group.com/doku.php?id=en:arm:tqma6ulx:mba6ulx:dip_switches|TQMa6ULx]] \\  [[https://support.tq-group.com/doku.php?id=en:arm:tqmls102xa:mbls102xa:dip_switches|TQMLS102xA]]
  * Interrupt Boot process in U-Boot
  * Determine the maximum 512-byte blocks usable for hardware partitioning:
<code>
mmc rescan
mmc maxhwpartsectors
</code>
++++ Example |
<code>
=> mmc rescan
=> mmc maxhwpartsectors
maxhwpartsectors: 6d4000
=>
</code>
++++
  * Check Partition configuration:
<code>
mmc hwpartition user enh 0 0x${maxhwpartsectors} wrrel on check
</code>
++++ Example |
<code>
=> mmc hwpartition user enh 0 0x${maxhwpartsectors} wrrel on check
Partition configuration:
        User Enhanced Start: 0 Bytes
        User Enhanced Size: 3.4 GiB
        User partition write reliability: on
        No GP1 partition
        No GP2 partition
        No GP3 partition
        No GP4 partition
