Xilinx Embedded Software (embeddedsw) Development

It seems that monitors capable of MST, upon switching to SST mode in the monitor options menu, respond with NACK when the segment pointer is written. These same monitors ACK segment pointer writes when running in MST mode. Tested monitors that are SST only monitors also ACK segment pointer writes. The issue here is that MST monitors running in SST mode will error out when the I2C read function is called because the segment pointer is always being written to 0 (segment pointer is reset), and thus receives a NACK. This patch prevents this from happening. From now on, if the user changes the segment pointer, it is up to them to reset it to 0. The I2C read will only increment the segment pointer when required to do a read outside of the base EDID block. Signed-off-by: Andrei-Liviu Simion <andrei.simion@xilinx.com> |

embeddedsw.git - repo for standalone software All software is version less and divided into three directories - lib contains bsp, zynq fsbl and software services like xilisf - license.txt contains information about the various licenses and copyrights - XilinxProcessorIPLib contains all drivers - ThirdParty software from third party like light weight IP stack - mcap software for using MCAP interface on Ultra Scale boards to program 2nd level bitstream Every driver/lib/apps/services has these sub-directories 1. data - contains tcl, mdd, testapp tcl or header files used in SDK 2. doc - documentation of source code in form of pdf or html 3. examples - illustrating different use cases of driver 4. src - driver interface code implementing functionality of IP <repo> |-XilinxProcessorIPLib | |- drivers | |- uartps | |- data | |- src | |- doc | |- examples | |-lib | |- bsp | |- standalone | |- data | |- src | |- cortexa9 | |- microblaze | |- common | |- profile | |- doc | |- xilkernel | |- data | |- doc | |- src | |- sw_apps | |- zynq_fsbl [described below] | |- sw_services | |- xilffs | |- xilskey | |- xilmfs | |- xilrsa | |- xilflash | |- xilisf | | Note - All these are libraries and utilize drivers | |-ThirdParty | |- sw_services | |- lwip140 | |-mcap | |-linux Building FSBL from git: FSBL has 3 directories. 1. data - It contains files for SDK 2. src - It contains the FSBK source files 3. misc - It contains miscelanious files required to compile FSBL for zc702, zc706, zed and microzed boards. It also contains the ps7_init_gpl.[c/h] with gpl header in respective board directories. How to compile FSBL: 1.Go to the Fsbl src directory "lib/sw_apps/zynq_fsbl/src/" 2. make "BOARD=<>" "CC=<>" a. Values for BOARD are zc702, zc706, zed, microzed b. Value for CC is arm-xilinx-eabi-gcc. Default value is also same. 3.Give "make" to compile the fsbl with BSP. By default it is built for zc702 board with arm-xilinx-eabi-gcc compiler 4.Below are the examples for compiling for different options a. To generate Fsbl for zc706 board i.make "BOARD=zc706" b.To generate Fsbl for zc702 board with debug enable and RSA support i.make "BOARD=zc702" "CFLAGS=-DFSBL_DEBUG_INFO -DRSA_SUPPORT" c.To generate Fsbl for zc706 board and compile with arm-xilinx-eabi-gcc with MMC support i.make "BOARD=zc706" "CC=arm-xilinx-eabi-gcc" "CFLAGS=-DMMC_SUPPORT"
