Part Number: AM6548

Hi TI,

On our AM6548 PG 2.0 custom board we are getting below errors from SPI Driver.

[ 144.892680] cadence-qspi 47040000.spi: Indirect write timeout

[ 144.898473] spi-nor spi7.0: operation failed with -110

In this case we are not using OSPI but we are using FRAM memory. we are storing few bytes of data to FRAM every 200 ms .

Thanks,

Hi Sarfaraz,

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1033521/tda4vm-an-indirect-write-completion-error-occurred-in-the-linux-ospi-driver/3821669#3821669

This seems to be the same Issue as well on a different SoC.

The workaround is to give more delays for now. This is still not fixed.

It has a workaround by adding delay. We will intimate the fixed issues in the next release. Currently we do not have a fix.

Hope this answers your question. If no other questions please click on verify answer.

Best Regards,
Keerthy
