E1M-X V2N-M1 is the V2N SoM with a DEEPX DX-M1 AI accelerator. Reading order is the V2N path plus a DEEPX-specific delta.

Reading order

  1. V2N one-pager + bring-up first — start with the V2N getting-started index (sibling category) — every V2N rule applies here too.
  2. V2N-M1 one-pager — docs/soms/v2n-m1.md.
  3. DEEPX bring-up delta — DA9292 PMIC sequencing for the DEEPX 0.75 V core rail, M1_RESET polarity (active-LOW), and the V2N-side rail-management GPIO map (DEEPX_PWR_EN_REQ on P65, DEEPX_CORE_0P75_EN on P64).

Recent DEEPX bring-up gotchas (worth reading before you wire it up)

  • DA9292 OTP-variant fix (2026-05-14) — the V2N-M1 OTP variant boots with CH2_VSTEP=1; writing the wrong byte over-volts DEEPX to 1.50 V. Driver clears CH2_VSTEP + CH2_EN together in a single PMC_CTRL_01 write before programming voltage.
  • DA9292_I2C_ADDR_V2N corrected to 0x1E — 0x1C was a placeholder.
  • M1_RESET polarity now ACTIVE_LOW by default — deepx_dxm1_set_reset_polarity() still lets carrier code override.
