MCUSDK-2131 | EtherCAT Slave increments long frame errors for frames with size less than 2000 bytes | EtherCAT Slave FWHAL | 7.3.0 onwards | AM64x, AM243x | Fixed |
MCUSDK-2202 | DDR: High bandwidth data traffic at certain burst patterns causes faiures. | High bandwidth data traffic at certain burst patterns on the DDR bus cause resonance frequencies on the DDR IO voltage rail. This in turn affects the DDR address bus and causes the failures. The main fix in the updated configurations is enabling write DBI on LPDDR4, and read DBI on DDR4. This helps to quite the data transitions on the DDR bus and greatly reduces the impact on the DDR IO voltage rail. | 8.1.0 onwards | AM64x, AM243x | Fixed. |
MCUSDK-2261 | CCS Target Configuration from SDK examples does not work | CCS | 8.1.0 | AM64x, AM243x | Added 1-click debug in the documentation which uses default target config itself.
