Fusing TX2i with secure boot keys does not have /sys/kernel/debug/bpmp/debug/ file system

Fused with R32.2.1
Flashed with OS created from R32.3.1.

The device was fused with earlier release since 32.3.1 fusing fails

I need the /sys/kernel/debug/bpmp/debug/ file system to access:

  • clk/aud_mclk/state
  • clk/nafll_nvdec/max_rate
  • nafll_nvenc/max_rate

The Audio Master Clock is the most important.

Is there a mechanism to restore the bpmp/debug directory?

The directory is not empty
ls /sys/kernel/debug/bpmp
clk_init mount ping trace trace_enable
module mrq tag trace_disable unmount

We’re investigating this issue, will do the update once clarified.

Once the device is production fused, debugfs is no more available
