TAQOZ Reloaded - invalid partition


I am using a P2 Eval Board - Revision C with an 4 GB SD Card and
TAQOZ Reloaded 2.8. If I start a picocom terminal session I get
the following output:

picocom v3.1

port is : /dev/ttyUSB0
flowcontrol : none
baudrate is : 921600
parity is : none
databits are : 8
stopbits are : 1
escape is : C-a
local echo is : no
noinit is : no
noreset is : no
hangup is : no
nolock is : no
send_cmd is : sz -vv
receive_cmd is : rz -vv -E
imap is :
omap is :
emap is : crcrlf,delbs,
logfile is : none
initstring : none
exit_after is : not set
exit is : no

Type [C-a] [C-h] to see available commands
Terminal ready


What is that message about an invalid partion about?
The SD card has one Win 95 FAT32 partition and it is
fomatted with the Windows 10 tool. What do I need to
do to get rid of that message.

Kind regards,

    Hi @fbou Fabian,
    My glossary has a section at the back called 'System Installation and Booting Up' which worked for me and my P2-EVAL. Your problem is probably due to either of two things:-
    1. An obsolete SD card that is not fully SDHC compatible. Modern Sandisk cards are known to work
    2. Taqoz may not support your chosen SD card format - using the SD association formatter would probably fix that
    Cheers, Bob

  • Thanks Super-Bob, I will try that later.

  • Hi @bob_g4bby Super-Bob,

    switching to a spare Sandisk SD card worked for me.
    Thanks a lot.


  • Good to hear you're up and running Fabian, hope you have some fun with Taqoz. I'm currently learning about serial input and decoding FMEA sentences from a gps module. Cheers, Bob

  • I remember Peter mentioned some issues with the SD vias (inductive capacitance?) of the P2-EVAL. I had SD issues with the KISS board, too, where using different clock speeds sometimes lead to problems. I have no skill or instruments to dig the source of such problems, at least until the SD is working with specific configs.
