 HAR-13062 | Known Issue | SD Card LED blinks if no SD Card is inserted | Aquila Development Board V1.3 | |
Customer Impact: The LED D14 can blink if no SD card is detected. Description: Due to back feeding through the ESD diodes the voltage of the CD# signal is too low. The system falsely detects an inserted card and tries to initializes it. |
| HAR-12027 | Known Issue | DDC signals and DSI bridge must be on different I2C buses | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: It is not possible to read the EDID of the displays with the Verdin DSI to HDMI adapter mounted on the Aquila DB. Description: The signals from DDC and the ones to the DSI bridge and EEPROM must be routed on two independent I2C buses or handled by an I2C bus switch. The Aquila Development Board does not implement this separation, resulting in a conflict between the EEPROM of the Verdin DSI to HDMI adapter and the EEPROM of the display, resulting in a corrupted EDID header. Workaround: Either force the EDID by software or remove the jumpers at I2C_3_DSI_SCL_B and I2C_3_DSI1_SDA_B and connect these pins with a jumper wire to another I2C bus. However, this requires small changes in the DSI to HDMI device tree overlay to assign the bridge to the correct I2C node. |
| HAR-11925 | Known Issue | Pull-up resistors might not have the expected value | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: Customers can face issues trying to read the EDID on displays connected to the Aquila Development Board, due to low resulting resistance on the I2C_3_DSI bus pull-up resistors. Description: On the Aquila Development Board, the pull-up resistors of the SDA and SCL lines of the I2C_3_DSI bus are merged in the jumper area. This means that the resulting pull-up resistance on the bus is ~0.935kOhm instead of 1.87kOhm, which may be too low for some displays, making it impossible to read the EDID. Workaround: If the bus resistance on the I2C_3_DSI bus seems too low, remove resistors R209 and R211. |
| HAR-11860 | Known Issue | DisplayPort DPCD/EDID Read May Not Work with Some Hardware | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: Customers may encounter issues using the DisplayPort interface with devices that rely on the AUX bus, such as certain converters. Description: The DisplayPort driver encounters issues reading the DPCD/EDID over the AUX bus when used with specific hardware, such as DisplayPort dummies, HDMI-to-DisplayPort converters, and potentially other devices. As a result, the device fails to function properly with the DisplayPort interface. Workaround: Using standard DisplayPort cables without any converters should function correctly. |
| HAR-11844 | Known Issue | Hissing noise coming from the DB power supply under high load | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: An audible hissing noise may be observed from the Aquila Development Board's power supply under high load, without any meaningful impact on board functionality. This behavior does not indicate any degradation in power supply performance. Description: Under high load, an audible hissing noise may be heard from the power supply, linked to its operational switching frequency. This occurs when powering the board through either the USB-C power delivery or the terminal block. |
| HAR-11746 | Known Issue | Left and Right Channels Swapped on Audio Jack | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: The left and right channel audio signals will be delivered inverted using the onboard audio jack. Description: The audio jack on the board has the left and right channels swapped. Both audio signals are delivered correctly, but their positions are reversed. |
| HAR-11139 | Known Issue | The RS485 interface is not functional | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: Customers can not use the onboard RS485 interface. Description: The Schmitt-trigger inverter connected to the UART_2 interface is improperly routed, rendering the onboard RS485 interface non-functional. Workaround: Use the jumper section to access the UART_2 interface and connect it to an external RS485 converter circuit. |
| HAR-11136 | Known Issue | Silkscreen text is swapped on jumper J19 | Aquila Development Board V1.2 | Aquila Development Board V1.3 |
Customer Impact: Customers should not rely on the silkscreen text for the pinout description of jumper array J19. Description: The labels next to the jumper array J19 are incorrect and do not correspond to their actual functions. Workaround: The jumper array J19 pin numbering is accurate and should be referenced in conjunction with the schematic to properly setup the board. |
