On bootup the emmc's hw partition is always set to 0 and the partition table is read from it. When switching to another hw partition the partition table's id is not updated but instead the old one from hw partition 0 is used. If there is no partition table on hw partition 0 then the code will terminate and return error even if the desired hw partition contains a perfectly fine partition table. This fix updates the partition table struct to correspond to the specified hw partition before testing if the partition table is valid or not.
