Hello Tiva_Tick53
On the TM4C129x device the sector size is 16KB, so all addresses have to be multiples of 0x4000.
There is a TI design which has a similar software where an image on SD Card is taken and loaded to external SDRAM.

Hello Prateek,
Then why are you using something that you do not understand. Stick to the known: An example for interfacing Macronix Serial Flash memory and the code collateral as given in the link below is more useful than AT45DB161 about which you…
On TM4C123x device you can use USB and SD cards as external storage, but a file system will be required. You might be able to connect a serial Flash too.
TM4C129x device has EPI. This allows the addition of external memory. Please refer the following…
Thanks Premi,
You might also like to look at one of our TI Designs that shows another methodology using SPI and EPI. It is located here: www.ti.com/.../TIDM-TM4C129SDRAMNVM
Hello Peitian,
Adding to what Robert said: SD Card will not be memory mapped for variable access. I would suggest referring to the reference design. Easy to construct and with software available.

Hello Elad
Thanks for the confirmation. The closest I have is a TM4C129x reference design where the image is copied from a SD Card to SDRAM and executed. But in principle the same can be used for internal Flash update.

Hello Priya
It is no a "evolution kit" but a "evaluation kit". I would suggest using the following TI Design example code which has a sd card example for the EK-TM4C1294XL.

Hello Jefferey,
Yes, they can use the Serial Flash from Micron as it seems to have the same structure as other serial flashes. However do note that we do not have a driver for this particular serial flash. The only one that you will see drivers for are…
Hi,
I try to develop driver for Serial Memory (MX66L51235F) .... for this purpose i refer to sample codes in www.ti.com/.../TIDM-TM4C129SDRAMNVM... . ""ektm4c129_qssi_example""...
I am ample to perform read/erase/write in spi mode…
