LP-AM263P (AM263P)

Quick facts

Get it running

First blink: 1 min 18 s from plug-in to a changed blink (terminal).

1. Tools: MCU+ SDK 26.01.00.08, CCStudio 21.0.1, TI Arm Clang 5.1.1.LTS, SysConfig 1.28.0. The SDK pins older versions (CCStudio 20.5.0, SysConfig 1.27.0, TI Arm Clang 4.0.4.LTS); the newer ones built every example tried
2. Build TI's blink: In examples/drivers/i2c/i2c_led_blink/am263px-lp/r5fss0-0_nortos/ti-arm-clang run make i2c_led_blink.release.out DEVICE=am263px PROFILE=release TOOLS_PATH=$HOME/ti CCS_PATH=/Applications/ti/ccs2101/ccs CGT_TI_ARM_CLANG_PATH=/Applications/ti/ti-cgt-armllvm_release SYSCFG_PATH=/Applications/ti/sysconfig_1.28.0
3. Open the console first: A reader on ...1 must be running before the load; the examples print once, milliseconds after start
4. Load: DSLite load -c am263p/AM263Px_ZCZ_C_<serial>.ccxml -t 120 i2c_led_blink.release.out into RAM; 4.4 to 7.6 s per 0.9 MB image, first load 78 s
5. Check: The reader prints I2C LED Blink Test Started ...; the LEDs go on, then off one at a time, ten times, about 16 s

Every step, with the setup: the board's README.

Fixes

• If you see Empty console after DSLite load, open ...1 before the load.
• If you see DSLite error -615, plug in the USB-C supply; delete the property.
• If you see ModuleNotFoundError: No module named 'construct', ignore it for a RAM load.
• If you see DSLite load times out at 90 s, run it again.
• If you see Error: Could not fetch next record for SQL statement (database disk image is malformed), remove the one slot no process holds.
• If you see Does not match the target endianness, not loaded on the third core, load that core once with the GEL connection file.
• If you see Console shows the previous program after a load, debugger System Reset.
• If you see Flash_norOspiPhyTune : PHY enabling failed!!! Continuing without PHY.., flash still works at 16.7 MHz; back up the sector at 0x80000 first.
