Known Issues and Limitations

Issue ID	Head Line	Module	Reported in Release	Affected Platforms	Workaround in this release
PROC_BRDS-658	MAC PORT 0 packet drop seen of Rx/TX - Packet drop is seen on MAC PORT0 (RGMII1) on 1Gbps mode on GESI board of J721E EVM alpha version. This port is labeled as PRG1_RGMII1_B in the GESI board connections figure in @ref ethfw_depend_evm_gesi_j721e section. This issue is not applicable to J721E EVM beta version	Alpha EVM	00.08.00.00	J721E	Reduce MAC port 0 speed to 100Mbps in J721E EVM alpha version.
PROC_BRDS-671	External 50MHz RMII clock from PHY is not connected by default to SoC's RMII_REF_CLOCK pin in GESI boards of J721E EVM alpha version This issue is not applicable to J721E EVM beta version	Alpha EVM	00.08.00.00	J721E	To get RMII_50MHZ_CLK, resistor R225 needs to be populated. Move R226 to R225 on GESI board to get this clock.
PROC_BRDS-659	QSGMII expansion board is causing instabilities in the MDIO bus in J721E EVM alpha version. After a few mins, MDIO register access fail. This issue is not applicable to J721E EVM beta version.	Alpha EVM	00.08.00.00	J721E	Disconnect QUAD PORT ETH expansion board from Alpha EVM.
ETHFW-607	EthFw - QSGMII daughter board not supported with Linux	EthFw	06.02.00.04	J721E	QSGMII daugther board is not supported in Linux due to SERDES sharing not enabled. In order to use QSGMII ports, SERDES usage from Linux has to be disabled. Contact TI representative for detailed instructions to enable QSGMII ports.
ETHFW-1733	demo: Rate limiting demo exceeded intended rate in egress port	EthFw	07.00.00.00	J721E, J7200	When sending packets at a rate higher than programmed in the demo (200Mbps), for instance 250Mbps, the egress port should see its rate limited to 200Mbps. But the rate at egress port is same as the ingress port.
ETHFW-1902	EthFw: ARP request fails in Linux virtual MAC (switch port) with static IP	EthFw	08.01.00.00	J721E, J7200	Replace default firmware in Linux with precompiled images from EthFw component directory.

Package Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit	Meaning	Description
1 (M=Major)	Major revision	Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
2 (m=minor)	Minor revision	Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch)	Patch number	Incremented for all other source code changes. This include any packaging support code.
4 (b=build)	Build number	Incremented for each release delivery to CM. Reset for any change to M, m or p.
