Just received from mouser a brand new STLink V3.

Here cames a bit of teardown of it.

Powered by an STM32F723 BGA variant.

It has a pretty nice construction with insightful features (USB to CAN, I2C, SPI, JTAG, SVD, SWIM).

I would love to use this a general tool. (Patch AVRDude to flash AVRs with it, patch flashrom to flash random SPI flashes, etc.)

Shipped with the latest FW:


The MB1440B is a kind of passive shield, just some protection diodes and a SN74LVC2T45 level shifter present for the SWIM.

Make sure that your types of your parameters on the MCU and the host matches...

One of our custom analyzer plugin started to fail to load after started using an std::set variable with the error above with the similar output from the Logic:

Solution:

Add -lc++ to the linker flags before the -lAnalyzer.

I have converted a project previously built with Cosmic to be compiled with SDCC.

The size results were really bad, the project cannot fit in the 8K memory of the STM8S003:

SDCC:

flash size: 6912 occupied: 8706 (125.95%) free: -1794 (-25.95%)

sensor size: 2092 (30.27%)
interrupt size: 1959 (28.34%)
signalprocessing size: 1577 (22.82%)
xlineslave size: 1309 (18.94%)
led size: 988 (14.29%)
init size: 253 (3.66%)
config size: 129 (1.87%)
delay size: 123 (1.78%)
seedbuffers size: 104 (1.50%)
main size: 86 (1.24%)
adc size: 86 (1.24%)


While Cosmic:

flash size: 6912 occupied: 6480 (93.75%) free: 432 (6.25%)

interrupt.o size: 1540 (22.28%)
sensor.o size: 1464 (21.18%)
xlineslave.o size: 802 (11.60%)
signalprocessing.o size: 688 (9.95%)
led.o size: 559 (8.09%)
ldiv.o size: 235 (3.40%)
init.o size: 222 (3.21%)
lmul.o size: 139 (2.01%)
config.o size: 131 (1.90%)
interrupt_vectors.o size: 128 (1.85%)
crtsi0.sm size: 80 (1.16%)
delay.o size: 73 (1.06%)
main.o size: 69 (1.00%)
adc.o size: 60 (0.87%)
seedbuffers.o size: 45 (0.65%)
imul.o size: 33 (0.48%)
lcmp.o size: 32 (0.46%)
lgadd.o size: 23 (0.33%)
lsbc.o size: 23 (0.33%)
lneg.o size: 21 (0.30%)
cmulx.o size: 20 (0.29%)
ludiv.o size: 20 (0.29%)
lgneg.o size: 19 (0.27%)

lursh.o size: 15 (0.22%)
lgursh.o size: 14 (0.20%)
utolx.o size: 7 (0.10%)


The total flash size is just 6912 bytes because of the bootloader.
