    Recently, we received some feedback from customers that they bought 2GB/32GB LattePanda 1st Gen boards, but the system shows 1GB RAM.
    The problem is because of CPU's bug and the production batch is August 2018, S/N:KBMP180808XXXXX. At present this problem has been solved already, and will not appear in the following batches.
    The possibility of this problem is very small, but If you have the same problem, please reflash the BIOS according to the tutorial below, so that your board can correctly identify the RAM.
