Hello,
After brief studying of t210 dts files it seems that CoreSight is supported on Nano:
ptm {
compatible = "nvidia,ptm";
reg = <0x0 0x72010000 0x0 0x1000>, /* funnel_major */
<0x0 0x72030000 0x0 0x1000>, /* etf */
<0x0 0x72040000 0x0 0x1000>, /* replicator */
<0x0 0x72050000 0x0 0x1000>, /* etr */
<0x0 0x72060000 0x0 0x1000>, /* tpiu */
<0x0 0x73010000 0x0 0x1000>, /* funnel_bccplex */
<0x0 0x73440000 0x0 0x1000>, /* ptm0 */
<0x0 0x73540000 0x0 0x1000>, /* ptm1 */
<0x0 0x73640000 0x0 0x1000>, /* ptm2 */
<0x0 0x73740000 0x0 0x1000>, /* ptm3 */
<0x0 0x72820000 0x0 0x1000>, /* funnel_minor */
<0x0 0x72a1c000 0x0 0x1000>; /* ape */
};
However ‘nvidia,ptm’ seems to be handled by outdated tegra_ptm_t210.c which no longer compiles. Can I find dts with support for coresight anywhere?
