Fixed detection and upload of driver for Mark 2 device#24
Conversation
WalkthroughRemoved kernel-version helper functions and replaced them with an early-captured kernel string; updated SJ201 boot image and made SJ201 button overlay board-aware; adjusted ReSpeaker/HiFiBerry/4-mic detection and i2c_device_name handling; hardened writing of detected device to /etc/OpenVoiceOS/i2c_platform.

69-71: Kernel version check: simplify and de-brittle (use glob match; drop sed trimming).The sed pattern assumes a dash followed by digits (e.g., 6.6.X-123), which doesn’t match common RPi kernels like 6.6.X-v8+ or 6.6.X+rpt—so the trimming does nothing. Since you only need to branch on 6.6.*, use a simple glob; it’s clearer and avoids regex pitfalls.
Apply this diff:
- # Variable to hold current kernel - local current_kernel=$(uname -r | sed -re 's/(^[0-9]*\.[0-9]*\.[0-9]*-[0-9]*)(.*)/\1/') + # Variable to hold current kernel (full string, e.g. "6.6.31-v8+") + local current_kernel + current_kernel=$(uname -r) @@ - if [[ $current_kernel =~ "6.6." ]]; then + if [[ $current_kernel == 6.6.* ]]; thenAlso applies to: 219-219
229-231: Guard the new firmware flash path; add fallback and error handling.Bumping to v4_2_0 is fine, but if the firmware file or flasher isn’t present, setup will fail silently or break SJ201 init on some images. Guard it and optionally fall back to the previous v4_1_0.

95-102: check_mark_1() was removed but is still called — this will break Mark-1 detection.This call will fail (function/command not found), setting mk1 empty and incorrectly falling back to WM8960. Either reinstate the function or guard the call.
Minimal guard suggestion (outside the changed lines):
# Safely detect Mark-1 only if helper is available if command -v check_mark_1 >/dev/null 2>&1; then mk1="$(check_mark_1)" else mk1="" fiIf Mark-1 support is intentionally dropped, remove this branch and associated amixer/dtoverlay ops to avoid misleading logs and dead code.
297-305: compare_kernel_version() usage is both undefined and syntactically wrong here.
- The helper appears removed; this results in a runtime failure.
- Even if present,
if $(compare_kernel_version "6.1.77"); thenis invalid: it tries to execute the function’s stdout as a command.Replace with a version compare using sort -V against kernel_base derived earlier.
Suggested replacement (outside the changed lines):
# Choose overlay based on kernel version >= 6.1.77 if [[ "$(printf '%s\n' '6.1.77' "$kernel_base" | sort -V | tail -n1)" == "$kernel_base" ]]; then dtoverlay hifiberry-dacplus else dtoverlay hifiberry-dacplus-pro fiIf you want me to push a patch that wires this with the earlier kernel_base change, say the word.

71-73: Simplify kernel capture; also derive a stable base for comparisons.The sed trim is brittle and unnecessary. Capture uname -r as-is and derive a base version via parameter expansion for later comparisons.
Apply this diff:
- # Variable to hold current kernel - local current_kernel=$(uname -r | sed -re 's/(^[0-9]*\.[0-9]*\.[0-9]*-[0-9]*)(.*)/\1/') + # Variables to hold current kernel full string and base (strip suffix after first '-') + local current_kernel="$(uname -r)" + local kernel_base="${current_kernel%%-*}"
221-229: Anchor the kernel check and avoid a quoted regex; use a glob against the base version.Quoting the regex is unnecessary, and matching a literal major.minor is clearer. Also, prefer comparing against kernel_base.
Apply this diff:
- if [[ $current_kernel =~ "6.6." ]]; then + if [[ $kernel_base == 6.6.* ]]; then
313-320: Optionally create the target directory before writing; keep the improved error handling.Currently, you error out if the directory doesn’t exist. Consider creating it to make first-boot flows smoother.
Apply this diff:
- if [[ -d "$(dirname "$i2c_device_file")" ]]; then + if [[ -d "$(dirname "$i2c_device_file")" ]] || mkdir -p "$(dirname "$i2c_device_file")"; then echo "$i2c_device_name" > "$i2c_device_file" || echo "Error: Failed to write to $i2c_device_file" >&2 else echo "Error: Directory $(dirname "$i2c_device_file") does not exist" >&2 fiOptionally, for safer writes: write to a temp file then mv into place to reduce partial-write risks.

106-108: Make kernel parsing robust and future-proof.The current sed extracts “X.Y.Z-build” only if it exactly matches “digits.digits.digits-digits”. Kernel strings often include +, rpt, rc, etc. Prefer extracting just the numeric X.Y.Z reliably.
Apply:
- local current_kernel=$(uname -r | sed -re 's/(^[0-9]*\.[0-9]*\.[0-9]*-[0-9]*)(.*)/\1/') + # Extract strictly the numeric part X.Y.Z from uname -r, ignoring any suffixes (+, -rpt, -v8, etc.) + local current_kernel="$(uname -r | sed -E 's/^([0-9]+\.[0-9]+\.[0-9]+).*/\1/')"
261-269: Use an exact-major.minor match for 6.6 kernels.The regex "6.6." treats dots as “any character” in [[ =~ ]]. Escape dots and anchor to start to avoid false positives (e.g., matching “16.6.x”).

353-363: Consolidated HiFiBerry block looks fine; keep this single source of truth.Post removal of the earlier conflicting block, this becomes the canonical path (overlay + optional headphone jack). Consider adding a brief comment here explaining kernel/board assumptions.

In ovos-i2csound around lines 223-224, the conditional requires both RESPEAKER6
and RESPEAKER4 to be true making the 6-mic branch unreachable; change the logic
to run when RESPEAKER6 is true and RESPEAKER4 is not true (or simply when

191-216: ReSpeaker 4-mic path looks correctOverlay + mixer init sequence and setting
i2c_device_name="RESPEAKER4"inside the block is appropriate.
287-291: Board-aware button overlay selection looks goodSelecting sj201-buttons-overlay-pi5 on RPI5 and the generic overlay otherwise is correct and clear.

Close both ends of FD 3 to avoid a persistent TTY handle leak
exec 3<>"$dev" opens FD 3 for read+write, but only the write end is closed. This leaks the read end and can hold the serial device open past function scope.
Apply this diff:
- exec 3>&-
+ # Close both read and write ends of FD 3
+ exec 3>&- 3<&-📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In ovos-i2csound around lines 89 to 91, the cleanup currently only closes FD 3's
write end which leaks the read end and can keep the TTY open; after using exec
3<>"$dev" explicitly close both ends of FD 3 (close the read and write
descriptors) — e.g. perform both the write-close and read-close (exec 3>&- and
exec 3<&- or a combined close) in the cleanup section so the serial device is
fully released.

Resolves #18 Note: This is just for detection and setup. Drivers still need to be installed, and the required files need to be available. |
