FTDI devices share +same serial number. openOCD connects to random board. DAP of powered-off +board doesn't respond. + +**Solution:** `adapter usb location "1-1.N"` in openOCD config. +Format: `bus-rootport.hubport` (NOT `bus-port`). + +### P4: DAP becomes inaccessible after CPU enters Linux + +**Diagnosis:** JTAG works initially, then DAP timeout after resume. + +**Root cause:** Linux enables MMU. DAP memory access goes through MMU. +If MMU page tables don't cover target address → translation fault. + +**Attempted fixes:** +- arm mmu off → command not found in openOCD 0.12 +- Write MMU disable code to OCM → patches overwritten by FSBL relocation +- JTAG ps7_init + direct kernel load → DDR3 data abort (wrong DDR3 timing) + +**Status:** SOLVED by using SD boot (avoids JTAG entirely after initial debug). + +### P5: Identical MAC — switch cannot route between boards + +**Diagnosis:** All 3 boards have MAC 00:0a:35:00:01:22. +Switch MAC table has one entry. Traffic goes to one port. +ARP collision: 3 replies for same IP with same MAC. + +**Impact:** Cannot run mesh daemon between boards. UDP packets +go to wrong board or get dropped. + +**Attempted fixes:** + +#### Fix attempt 1: Runtime `ip addr add` (ARP dance) +- arp -d .10 → SSH → ip addr add .11 → arp -d → SSH → ip addr add .12 +- Result: WORKS temporarily. IPs lost on power cycle (ramfs). +- Problem: switch still sees same MAC, routing unreliable. + +#### Fix attempt 2: uEnv.txt ethaddr change (unique MAC per board) +- Change `ethaddr=02:00:00:00:00:0N` in uEnv.txt +- Result: MAC DOES change! U-Boot patches device tree local-mac-address. +- But: IP still .10 (from ramdisk /etc/network/interfaces). + +#### Fix attempt 3: uEnv.txt ethaddr + ipaddr +- Also change `ipaddr=192.168.1.1N` +- Result: ipaddr is U-Boot's own IP, NOT Linux kernel IP. +- Linux ignores U-Boot ipaddr. + +#### Fix attempt 4: uEnv.txt ethaddr + boardargs (kernel ip= parameter) +- Add `boardargs=setenv bootargs ${bootargs} ip=192.168.1.1N:::255.255.255.0::eth0:off` +- Add `uenvcmd=run boardargs; run sdboot` +- Result: INFINITE RECURSION! sdboot → uenvboot → uenvcmd → sdboot → ... +- Board hangs, never boots. + +#### Fix attempt 5: Runtime `ip link set eth0 address` (MAC change at runtime) +- Result: Network link drops immediately. Board unreachable. +- Must power-cycle to recover. MAC reverts on reboot. + +#### Fix attempt 6: Ramdisk modification (S99tri-net auto-IP script) +- Extract uramdisk.image.gz, add /etc/init.d/S99tri-net +- Script reads MAC, sets matching IP automatically +- First attempt: uImage header CRC mismatch → U-Boot rejects +- Second attempt: mkimage -T ramdisk → proper CRC +- Result: Board STILL doesn't boot. Unknown cause (possibly cpio format issue). + +**Current working approach:** +- uEnv.txt ethaddr ONLY (unique MAC, proven working) +- Runtime ip addr add for unique IP (not persistent) +- ARP dance to reach different boards + +### P6: Kuiper BOOT.BIN vs Vendor BOOT.BIN + +**Diagnosis:** Two BOOT.BIN candidates: +- Kuiper (from PZ_P201_3_MINI_Openwifi-005.img): 4.7MB +- Vendor (from P201Mini ZIP 001 SD-BOOT): 2.9MB + +**Result:** +- Kuiper BOOT.BIN: PL Ethernet doesn't come up. No eth0. + FSBL runs (PLLs lock), but PL bitstream doesn't configure Ethernet PHY. +- Vendor BOOT.BIN: Everything works. PL Ethernet OK. + +**Root cause:** Kuiper bitstream is for a different board variant. +Vendor bitstream has correct PL Ethernet IP for P201Mini. + +**Solution:** ALWAYS use vendor BOOT.BIN (2.9MB from ZIP 001). + +### P7: Board 1 permanently dead (JTAG MMU damage) + +**Diagnosis:** Board 1 was subjected to extensive JTAG experiments: +- ps7_init (PlutoSDR version, wrong DDR3 timing) +- MMU disable code loaded to OCM +- U-Boot loaded via JTAG +- Kernel loaded to DDR3 at 0x10000000 +- FSBL patching (NOP park calls) +- PSS_RST_CTRL soft resets + +**Current state:** +- JTAG TAP detection: OK (PL + CPU taps found) +- DAP examination: CPU0 MPIDR found +- PLL_STATUS @ 0x10C: data abort (MMU translation fault) +- DDR3 access: data abort (MMU translation fault) +- SLCR access: data abort (MMU translation fault) + +**Root cause:** JTAG-loaded code enabled MMU. MMU page tables in DDR3. +DDR3 controller may be in bad state (PlutoSDR ps7_init ≠ P201Mini DDR3). +MMU persists across soft resets. Cannot access any peripheral. + +**Recovery options:** +1. Vivado/XSDB Hardware Manager (proper JTAG recovery) +2. Zynq Boot ROM + fresh QSPI flash via JTAG +3. Physical POR (if available — nGST button not found) +4. Replace board + +### P8: SD card wear (20+ erase cycles) + +**Diagnosis:** SD cards used for 20+ erase/write cycles in one session. +Flash memory has limited write endurance (~1000-10000 cycles for TLC). + +**Symptoms:** +- Files written correctly (size matches) +- U-Boot reads BOOT.BIN successfully (FSBL runs, PLLs lock) +- But uImage/ramdisk reads fail silently +- Board hangs in U-Boot after FSBL + +**Root cause:** Flash cells degraded. Read errors on later sectors. +BOOT.BIN (first 2.9MB) reads OK. uImage (4.3MB at offset ~2.9MB) fails. + +**Solution:** Use FRESH SD card. + +### P9: Boot switch position — IRRELEVANT + +**Discovery:** P201Mini boot switch (JTAG / QSPI-SD) does NOT affect SD boot. +SD card presence is auto-detected by bootROM regardless of switch position. +- Switch JTAG + SD inserted → boots from SD +- Switch QSPI/SD + SD inserted → boots from SD + +**Impact:** Wasted time asking user to change switch position. +Board 1 was NOT dead from switch — it was dead from JTAG MMU damage. + +### P10: macOS limitations + +**Diagnosis:** Multiple macOS-specific blockers: + +- **Raw disk write blocked:** dd if=image of=/dev/rdisk4 → "Operation not permitted" + Even with sudo. macOS SIP blocks raw device access. + Fix: use diskutil eraseDisk + cp (filesystem level). + +- **FTDI card reader conflict:** When FTDI (board USB) is connected, + card reader not detected. Must disconnect board to use card reader. + +- **SSH host key changes:** Each board boot generates new SSH host key. + Must clear known_hosts every SSH session. + Fix: `-o UserKnownHostsFile=/dev/null`. + +- **sshpass in Rust:** `/opt/homebrew/bin/sshpass` needed full path. + Rust Command::new("sshpass") fails if not in PATH. + +--- + +## 3.
