Description: TPM interrupt is not working, driver is working in polling mode, the driver fallback to polling mode with this error `tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling instead`. Workaround: TPM is working fine despite this issue, no known drawback when using polling mode and no firmware bug is present. Commit `e644b2f498d2 ("tpm, tpm_tis: Enable interrupt test")` from mainline kernel can be back-ported if needed. |
| ELB-5339 | Feature Request | Add usrmerge Distro Feature | Apalis iMX6, Apalis iMX8, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin AM62, Verdin iMX8M Mini, Verdin iMX8M Plus | | | | No |
Description: systemd now requires the usrmerge distro feature.
This creates the symlinks /bin, /sbin, /lib, and /lib64 pointing to their /usr/... counterparts and places their content into the /usr/bin .. directories. |
| Upcoming Embedded Linux BSP Q2 2024 Quarterly Release |
| ELB-5644 | Known Issue | Watchdog Not Working Correctly (Unexpected Reset). | Verdin AM62 | Watchdog | | Low | No |
Description: It's not possible to feed the AM62 watchdog from systemd using the RuntimeWatchdogSec setting. The module enters a boot loop when this setting is enabled. Workaround: Apply patch https://lore.kernel.org/all/20240404153319.1088644-1-jm@ti.com/ to the Linux Kernel. |
| ELB-5435 | Known Issue | Audio Playback/Recording Fails Sporadically | Verdin AM62 | Analog Audio | | Low | No |
Description: Occasionally, following a system reboot, is not possible to play/record audio on the sound card, despite the apparent normal functionality of the sound subsystem. This issue arises from a race condition within the kernel's audio driver controller. |
| ELB-5326 | Feature Request | Fix Spurious Error Messages ("ERROR: reserving fdt memory region failed") | Verdin AM62 | Bootloader | | | No |
Description: Some spurious ERROR messages are print at boot
```
ERROR: reserving fdt memory region failed (addr=9cb00000 size=100000 flags=4)
ERROR: reserving fdt memory region failed (addr=9cc00000 size=e00000 flags=4)
ERROR: reserving fdt memory region failed (addr=9da00000 size=100000 flags=4)
```
Workaround: These error messages can be safely ignored. Alternatively EFI could be removed from the U-Boot configuration. |
| ELB-4916 | Feature Request | Make Alsa Configuration Read Only Rootfs Friendly | Verdin AM62, Verdin iMX8M Mini, Verdin iMX8M Plus | Analog Audio, Buildsystem | | | No |

| ELB-5600 | Feature Request | Improve CAN Interfaces Naming | Verdin AM62, Verdin iMX8M Mini, Verdin iMX8M Plus | | | | No |
Description: Improve the naming of the CAN interfaces adding network alternative name. This improvement aims to synchronize CAN references across device trees, device schematics, and Linux naming (e.g. Verdin AM62 MCU CAN0 is named verdin-can2 as an alternative name with this change). |
| ELB-5592 | Feature Request | Change 0071/0072 Verdin AM62 Solo To HSFS SoC | Verdin AM62 | Bootloader, Buildsystem | | | No |
Description: Starting from Verdin AM62 V1.1B HW Revision HSFS SOC is used and this change requires using a different firmware file. Previous HW variants will fail to boot after this change. Workaround: Using old variants is still possible using the previous GP firmware ("tiboot3-am62x-gp-verdin.bin"). For example, the tezi JSON file can be edited replacing "tiboot3-am62x-hs-fs-verdin.bin" for the relevant product ids. |
| ELB-5589 | Feature Request | Update U-Boot to TI Release 09.02.00.009 Release | Verdin AM62 | Bootloader | | | No |

| ELB-5325 | Known Issue | CPU Starting At Wrong Frequency On 1GHz PID4s (0071, 0072) | Verdin AM62 | Bootloader, CPU | | Low | No |
Description: The CPU is always starting at 1.2 GHz, even on SKU with SOC that is rated maximum at 1.0GHz (PID4 0071 and 0072).
Kernel warning: `cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 1200000 KHz, changing to: 1000000 KHz` Workaround: No known malfunction is known because of this issue. |
| ELB-5301 | Feature Request | Improve WM8904 driver when MCLK is not multiple of the sample rate | Verdin AM62 | Analog Audio, Kernel | | | No |
Description: Playing audio on a Dahlia Carrier Board using a Verdin AM62 causes distortion on the audio output when using a sample rate different from 48kHz. Workaround: Use 48kHz sample rate or the `default` audio card. |
| ELB-5243 | Feature Request | Add RT Kernel Variant | Verdin AM62 | Kernel | | | No |

Description: Restarting hostapd makes it impossible for clients to connect to the AP. Workaround: Reboot the system after a hostapd configuration change. It's also possible to rmmod / modprobe mwifiex before restarting hostapd to apply the configuration change without a reboot. |
| ELB-5478 | New Feature | Update Linux Kernel to TI Release 09.01.00.006 | Verdin AM62 | Kernel | | | No |

Description: It's not possible to use the gpio-poweroff driver, as it's initialization fails with "gpio_poweroff_probe: pm_power_off function already registered" whenever the driver is configured on the device-tree. |
| ELB-5233 | New Feature | Add Bluetooth Support | Verdin AM62 | Bluetooth | | | No |
Description: Add Bluetooth Support. |
| Embedded Linux BSP Q3 2023 Quarterly Release |

Description: A getty is wrongly spawned on Verdin UART4 (ttyS3) |
| ELB-5307 | Fixed | Memory Overlap/Clash On 512MB SKU (0071, 0072) | Verdin AM62 | Bootloader | | Low | No |
Description: On Verdin AM62 SKUs with 512MB memory (0071, 0072) there is a memory overlap between the relocated U-Boot and some DT reserved memory (that is used by other firmware components). |
| ELB-5241 | New Feature | Update To TI Linux Kernel 6.1 | Verdin AM62 | Kernel | | | No |
Description: Update TI Linux Downstream Kernel To TI v6.1 |
| ELB-5236 | New Feature | Update U-Boot to ti-u-boot-2023.04 | Verdin AM62 | Bootloader | | | No |
Description: Update Downstream TI U-Boot To TI 2023.04 |
| ELB-4998 | Fixed | CTRL_SLEEP_MOCI# Low In U-Boot And Yavia I2C_1 EEPROM Not Working | Verdin AM62, Verdin iMX8M Mini, Verdin iMX8M Plus | Bootloader, I2C, Power Management | | Low | No |
Description: U-Boot is not properly driving the CTRL_SLEEP_MOCI# signal, because on that some carrier board peripheral might not be powered while in U-Boot.
For this reason the Carrier Board EEPROM on I2C_1 bus is not working properly on the Yavia Carrier Board.
This prevents the board to boot on Verdin AM62 + Yavia.
On Verdin iMX8MM and iMX8MP the following errors are printed every boot:
```
wait_for_sr_state: Arbitration lost sr=93 cr=80 state=2020
i2c_init_transfer: failed for chip 0x57 retry=0
i2c_idle_bus: failed to clear bus, sda=0 scl=0
i2c_init_transfer: give up i2c_regs=0x30a50000
get_tdx_eeprom: cannot find EEPROM by node
``` Workaround: Verdin iMX8MP and iMX8MM boot fine despite this bug. If needed CTRL_SLEEP_MOCI# can be driven from U-Boot command line using the `gpio` command. |
| Embedded Linux BSP 5.7.5 Maintenance Release |
| ELB-5484 | Known Issue | AP Does Not Work Anymore After `hostapd` Restart | Apalis iMX8, Colibri iMX6ULL, Colibri iMX8X, Verdin AM62, Verdin iMX8M Mini, Verdin iMX8M Plus | Wi-Fi | | Low | No |
Description: Restarting hostapd makes it impossible for clients to connect to the AP. Workaround: Reboot the system after a hostapd configuration change. It's also possible to rmmod / modprobe mwifiex before restarting hostapd to apply the configuration change without a reboot. |
| ELB-5731 | Known Issue | systemd-backlight Service Fails With a Read-Only Root Filesystem | Apalis iMX6, Apalis iMX8, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin AM62, Verdin iMX8M Mini, Verdin iMX8M Plus | Buildsystem | | Low | No |
Description: With a read-only root filesystem, the systemd-backlight@backlight:backlight.service cannot save the brightness value because it needs to write to a file on the root filesystem. |
| ELB-5450 | Known Issue | Audio Signal Distortion on Dahlia Carrier Board | Verdin AM62 | Analog Audio | | Low | No |
Description: Playing audio on a Dahlia Carrier Board using a Verdin AM62 causes distortion on the audio output. Workaround: Use 48kHz sample rate or the `default` audio card |
