The TPU Debugger code lists:

static const char *tpu_addr_name[0x1f] = {

[0] = "TSP_CTLR1",

[1] = "TSP_CTRL2",

[4] = "TSP_TX_1",

[3] = "TSP_TX_2",

[2] = "TSP_TX_3",

[5] = "TSP_TX_4",

[6] = "TSPACT_L",

......

Was wondering if the numbering is a typo. Could not find documentation online.

Just bringing to your notice for check.

Could you please confirm that items 2,3,4 are not supposed to be in sequence.

Thanks.
