Hi,

In RM0433 Reference Manual there is a description of the AXIM indicating the possibility to change the QoS for the AXI switch matrix, but cannot find the reference for the indexes used in AXI_INIx_READ_QOS or AXI_INIx_WRITE_QOS.

If there any manual where the channels are described?.

Regards,

Luis

Thanks for the answer, but I do not understand it yet.

According to AXI interconnect - INI x read QoS register (page 118) , the possible index for the offset range from 1 to 76 (Address offset: 0x41100 + 0x1000 * x, where x = 1 to 76). The figure 2 indicates 6 masters and 7 slaves, could you please elaborate the relationship between the master/slave and index of the register?

For example, whitch master/slave are affected with index 35?.

Regards,

Luis
