pocket beagle 2 bare metal application question

General Discussion
1

I have built the bare metal SBL for the pocket beagle 2 that Chalandi released. I built on Ubuntu using version 12.00.0027 of the TI mpu_plus_sdk. I have also built some of the example apps that are in that SDK. When I look at the applications that I built, I see multiple output files. For example:

.release.appimage

.release.appimage.hs_fs

.release.appimage.xip

.release.appimage.rprc

.release.appimage.rprc_xip

My question is: Which one(s) of these do I need to use with Chalandi bare metal SBL?

have you looked in Tools/sd_card

seems to have something that does sdcard thing

where is the .bin file ?

	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).bin     2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).dis     2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).elf     2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).hex     2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).map     2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).readelf 2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).sym     2>/dev/null || true
	@-rm -rf $(OUTPUT_DIR)/$(PRJ_NAME).uf2     2>/dev/null || true
	@-rm -rf $(OBJ_DIR)                        2>/dev/null || true

I believe that the bin file is only built if the ATF_INTERGRATED_BOOT flag is set.

The TI SDK that I am using does not have a tools/sdcard directory.

The rm list that you posted is from the no SDK Chalandi release, not the “with” SDK version that I am using. And the non SDK makefile clean does not work if used from Clean.sh. You will not see the error as the rm cmd line is piping stderr to /dev/null.

Amf99, Thanks for the reply. I see the disconnect between us. You thought I was using the no SDK Chalandi release and I thought you were replying about the “with” SDK Chalandi release which is what I am using. I did not make any changes to the SDK example apps but Chalandi did do all the work on the no sdk release, So maybe that is how he decided to name the application file with the .bin at the end. He could have given it any extension name because what is named in the config.txt file is what matters.
