From 30b0e9af8d1e68ee051ac62dd0e27c920fb396bd Mon Sep 17 00:00:00 2001 From: Phil Kirkpatrick Date: Tue, 9 May 2023 11:04:24 +0200 Subject: tcl/target: Add support for TMS570LC43xx Added support for TMS570LC43xx series parts. This uses the pre-existing ti_tms570.cfg parent config. In ti_tms570.cfg, dbgbase was changed. Note 1: Based on the following TI E2E post, the previous dbgbase was wrong and the new value isn't due to a difference in parts. Link: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1106954/tms570ls3137-debugging-with-openocd Note 2: Both the previous dbgbase and the one suggested in the TI E2E post have the 2 LSB set. In the current version of OpenOCD, this will cause cortex_a_read_cpu_memory_fast and cortex_a_write_cpu_memory_fast to fail due to an alignment checks in mem_ap__buf_noincr()->mem_ap_(). In all other uses of dbgbase for arm cortex parts, the 2 LSB are masked and ignored.

This chip features a Cortex-M4F with 512 KiB of flash on all the available versions, although the documentation suggests that there might be 256 kB versions as well. The initial support allows to read, erase and write the whole user flash area. Three new sub-commands under the new "qn908x" command are added in this patch as well: disable_wdog to disabled the watchdog, mass_erase to perform a mass erase and allow_brick to allow programming images that disable the SWD interface. Disabling the watchdog is required after a "reset halt" in order to run the CRC algorithm from RAM when verifying the chip. However, this is not done automatically on probing or other initialization since disabling the watchdog might interfere with debugging real applications. The "mass_erase" command allows to erase the whole flash without probing it, since in some scenarios the chip can be locked such that no flash or ram can be accessed from the SWD interface, allowing only to run a mass_erase to be able to flash the program. The flashing process allows to compute a checksum, similar to the lpc2000 driver "calc_checksum" but done over a different region of the memory. This checksum is required to be present for the QN908x bootloader ROM to boot, and otherwise is useless. As with the lpc2000 design, verification when using "calc_checksum" is expected to fail if the checksum was not valid in the image being verified. This was manually tested on a QN9080, including the scan-view, AddressSanitizer/UBSan and test coverage configurations.
