5. Silicon Errata - MCAL Support and Workarounds

5.1. Overview

This document tracks Silicon Errata coverage for AM263x Sitara MCU within the MCAL (Microcontroller Abstraction Layer) implementation. Each errata is identified by an errata ID and mapped to its MCAL support status.

Silicon Revision Analyzed: 1.0A, 1.1

5.1.1. Reference Documentation

For complete details on each errata, including workaround procedures and technical background, refer to the official device errata document:

AM263x Silicon Errata (SPRZ488F)

This document contains the complete errata specifications, including severity levels, workaround details, and implementation guidance for each silicon errata.

5.2. Errata Summary

i2311	UART	Spurious DMA Interrupts	YES	1.0A, 1.1	The MCAL restricts RX/TX trigger levels to pre-defined power-of-2 compliant values, effectively preventing the spurious DMA interrupt condition described in i2311
i2313	GPMC	Sub-32-bit read issue with NAND and FPGA/FIFO	NA	1.0A, 1.1	Not applicable - GPMC module not supported in current MCAL

i2350	McSPI	McSPI data transfer using EDMA in ABSYNC mode stops after 32 bits	NO	1.0A, 1.1	Application must configure EDMA in ASYNC mode for McSPI TX (or if ABSYNC is required, set acnt=4, bcnt=1, ccnt=1).
i2352	CONTROLSS-SDFM	Dynamically Changing Threshold Settings triggers Spurious Comparator Events	NA	1.0A, 1.1	SDFM module not supported in current MCAL version

i2356	CONTROLSS-ADC	Interrupts may Stop if INTxCONT not Set	PARTIAL	1.0A, 1.1	The continuous mode is NOT enabled by default during ADC_Init(). Application must explicitly call Adc_SetInterruptContinuousMode() for each group to enable the workaround
i2357	CONTROLSS-ePWM	ePWM Glitch if Trip Remains Active at End of Blanking Window	NO	1.0A, 1.1	MCAL does not provide blanking window register control
i2358	CONTROLSS-ePWM	Trip Events Not Filtered by Blanking Window for First 3 Cycles	NO	1.0A, 1.1	MCAL does not provide blanking window register control
i2359	CONTROLSS-CMPSS	Prescaler counter behavior different when DACSOURCE reconfigured	NO	1.0A, 1.1	If dynamic DAC source reconfiguration required during operation, application must perform soft reset between reconfigurations per device errata workaround

i2394	SOC CONTROL	Race condition in interrupt aggregator capture registers	NO	1.0A, 1.1	Application must implement workaround in all aggregator-based ISRs. Primarily required in DMA ISR and CAN ECC error ISR per device errata specification

i2401	CPSW	Host Timestamps Cause CPSW Port to Lock up	YES	1.0A, 1.1	Workaround: Disable host TX timestamps (TS_TX_HOST_TS_EN=0U).
i2402	CPSW	Ethernet to Host Checksum Offload does not work	YES	1.0A, 1.1	Hardware offload disabled. Software fallback: Pseudo checksum functions (Eth_genPseudoCheckSumIPv4/IPv6) compute TCP/UDP checksums in Eth_Priv.c

i2500	LIN	LIN Module Fails to Wake Up with 0xF0 as Wake-Up Key	YES	1.0A, 1.1	Use LIN header with ID 0x3C instead of raw 0xF0 byte. Lin_SetIdByte(lin_base_cntr_addr, LIN_WAKEUP_ID) — Uses 0x3C (ID 60) — Avoids deadlock caused by raw 0xF0 interpretation
