| | 323 | == VN14 GW7020-E Interrupt Voltage Translator Incompatibility |
| | 324 | |
| | 325 | Issue: |
| | 326 | * The revision E of the GW7020 SOM (i.MX8MP) for the GW7xxx Venice SBCs drives the GSC_IRQ# at an invalid voltage level causing a stuck interrupt. Linux will detect excessive spurious interrupts after about 5 to 6 minutes and disable the interrupt which lets you access devices on the GSC I2C bus fine just without interrupt support (meaning no interupt based timing events such as Tamper, 1x PB press, PB long hold) |
| | 327 | |
| | 328 | Workaround: |
| | 329 | * If you do not need GSC interrupts (not tracking interrupt driven tamper or pushbuton timing events), you can disable GSC interrupts with a kernel code change. Contact support@gateworks.com for details. |
| | 330 | |
| | 331 | Resolution: |
| | 332 | * This will be resolved in hardware on future hardware revisions (revision F) |
| | 333 | |
| | 334 | Affected Products: |
| | 335 | * GW7020-E SOM (IMX8MP) with any Venice GW71xx, GW72xx, GW73xx (aka GW7xxx-2x-xE) . This does not affect any VeniceFLEX (GW8xxx) which also uses the IMX8MP SOM. |
