The problem is the msp430.dylib driver shipped with pio.
I installed the Texas Instruments GCC Toolchain 9.2.0 (MSP430-GCC-OPENSOURCE IDE, configuration, compiler or debugger | TI.com) and replaced the original version on ~/.platformio/packages/tool-dslite/DebugServer/drivers with the Texas one.
It succeeded loading the binary onto the board. I don’t know yet how to debug with pio to check if it is all.
