IMX6UL SSPI command

anshulkhare — Tue, 02 Jan 2018 14:10:06 GMT

Hello All,

i have an IMX6UL board .

i am performing SPI interface test in U-Boot. Earlier SSPI command was not enabled,

so i updated config file with CONFIG_CMD_SPI for our board and in U-Boot command the sspi command is appearing,

but when i am trying to use this, i get the following error:

"unsupported opcode a0

Error -5 during spi transaction"

I ran the following command:

sspi 0:1.0 32 A

Could anyone please help me figure out what the issue is ?

When does this unsupported opcode error occur?

Hi Anshul,

You need configure the dtb, as well.

MX6UL just support QSPI NOR flash in SSPI, that the reason you are receiving "unsupported opcode".

Hello Anshul,

Did you resolve this issue ? Is it related to dtb ?

Thanks
