  Hello!
  Pico Pro Max bootloader does not "see" SanDisk Ultra 32GB microSDHC UHS-I card with ubuntu image.
  Does bootloader support cards more than 8GB? Does it support SDHC or SDXC card types?
  
  Make all by wiki manual, no any errors on format or making sd in SocToolKit.
  
  2GB card shows on boot
  

  Code: Select all

  mmc@ffa90000: 0, mmc@ffaa0000: 1 (SD)
  Bootdev(atags): mmc 1
  MMC1: Legacy, 52Mhz
  

  32GB card unrecognized...
  
  Thanks!
  

  

  
  UDP: board can access card after booting from flash, when insert card dmesg shows:
  

  Code: Select all

  [   26.881397] mmc_host mmc1: Bus speed (slot 0) = 49500000Hz (slot req 50000000Hz, actual 49500000HZ div = 0)
  [   26.881620] mmc1: new high speed SDHC card at address 0001
  [   26.885443] mmcblk1: mmc1:0001 SD 29.1 GiB
  

  seems problem in bootloader...
