AM2634: UART boot on AM263x / Errata i2371

Part Number: AM2634

Dear TI team,

we're looking into the AM263x for a project that involves booting from UART.

From the AM24x/AM64x we're aware of i2371 that says UART boot is unusable because the software workaround for i2310 isn't implemented in the ROM.

The AM263x errata (Rev. D) lists only i2310 but not i2171. Does that mean this workaround is implemented on the AM263x, and UART boot is usable?

Best Regards,

Dominic

    Hi ,

    The errata is not valid for AM26 device family as the requirement for the issue to be reproduced is the CPU clock should be over 600MHz. In case of K3 devices like AM24x/AM64x the R5F ROM, CPU runs at 800MHz but in case of AM26 devices, the CPU runs at 400MHz. So the issue is not valid for this device.

    I hope this helps.

    Best Regards,
