Hello there,
I am currently using the TE0820-03-03CG-1EA REV.3 together with the Carrier board TE0706-02.
For my project I need to flash the eMMC and QSPI over JTAG.
Under the CPLD firmware readme package are the following firmware options available:
Revision 04 for TE0820-03:
-SC0820_REV03_qspi.jed -> QSPI or JTAG Boot Mode can be selected
-SC0820_REV03_sd.jed -> JTAG or SD Boot Mode can be selected
-SC0820_REV03_qspi_sd.jed -> QSPI or SD Boot Mode can be selected (default firmware)
-SC0820_REV03_qspi_sd_jtag.jed -> QSPI or SD Boot Mode or JTAG can be selected (JTAG selection over NOSEQ Pin, check carrier, if this can used)
And on the website are:
Available CPLD Firmware
TE0820 CPLD - Firmware description with different Variants for PCB REV03 and newer
QSPI / SD /JTAG /eMMC Boot Modi - Default delivered, QSPI or SD Boot Mode is selectable via Boot Mode Pin and carrier depended PGOOD Pin can be used to select JTAG or eMMC Boot
QSPI / JTAG Boot Modi - Use QSPI or JTAG Boot Mode is selectable via Boot Mode Pin
JTAG / SD Boot Modi - SD or JTAG Boot Mode is selectable via Boot Mode Pin
QSPI / SD Boot Modi, QSPI or SD Boot Mode is selectable via Boot Mode Pin
From this I would be more interested in the first option: QSPI / SD /JTAG /eMMC Boot Modi (But here is the PGOOD pin used instead).
My question is what firmwares can I use and which signals (PGOOD / NOSEQ) are used or valid ?
And more important how can I make sure that they are working?
I would appreciate if you could shed any light on this topics.
Many thanks.
