What is the UART send/receive buffer size in the onboard XDS110 device of the TMDS273GPEVM?
Is the SOP3_MSS_UARTB_TX signal buffer size 1023 bytes?

- The UART buffer sizes in the onboard XDS110 are as follows:
It has a Programmable FIFO length, including 1-byte deep operation providing conventional double-buffered interface.
- The UART Rx and Tx FIFO queue sizes are 64 Bytes in the UART driver for AM273x.
- When you talk about the MSS_UARTB_TX signal you are referring to the AM273x UART (and not the XDS110 UART right?). AM273x-EVM MSS_UARTB_TX signal buffer would also be 64 bytes in size.
You're using the terms MSS_UARTB and XDS110 in the same sentence. It is not correct,
MSS_UARTB is the UART port terminology used in the AM273x MCU i.e., Sitara products
When you say XDS110 it is the emulator device, which is a seperate microcontroller named TM4C129 that is programmed to work as an emulator. This is a common debugger used for all the EVM boards we have.
So, if you want to know regarding XDS110 I will route it to our Tools team, any info required regarding AM273x is already shared by Shaunak in the previous reply.
