Other Parts Discussed in Thread: OMAPL138, OMAP-L132
Hi,
My customer has questions how DSP core is boot-up in OMAP-L138.
He refers to below two documents.
OMAPL138/C6748 ROM Bootloader Resources and FAQ:
https://www.ti.com/lit/an/spracm8/spracm8.pdf
Using the OMAP-L132/L138 Bootloader:
https://www.ti.com/lit/an/sprab41f/sprab41f.pdf
Now he understood ARM bootloader runs first, then UBL(user boot loader) wakes up DSP according to section 3.2 in spracm8.pdf.
Questions:
Q1) Where ARM bootloader loads the UBL binary? The address can be specified by user?
Q2) When UBL wakes up DSP, DSP code is loaded by UBL? If so which memory location?
Or DSP bootloader runs next?
Q3) In section 3.2.2 in spracm8.pdf, there is a link to sample code and bootable images.
https://git.ti.com/cgit/apps
But it seems no such software anymore. Where can I find the sample code?
Thanks and regards,
Koichiro Tashiro
