Hi, I am using ULINKpro D and JTAG connection to program a Cortex M7 baremetal device. Although ULINKpro D seems to be installed correctly (device manager - USB) and the connection between ULINKpro D and my DU seems okay, I cannot connect the debugger and this page shows up;
Also I get an error in Console:
Unable to connect to device ARMCS-DPI tried a couple of changes and I have this error as well:
Detected number of devices = 136, maximum allowed = 128. This problem is usually a result of the scanchain not acting correctly when using JTAG scans to count the number of devices.Does anyone know how to solve it?The only thing that has to be mentioned is that I am using 20 to 20 pin adaptor provided in the package of ULINKpro D.Thanks & regards
Hello!Thanks again.Appreciate your kind cooperation.
Hi again!When we used malloc of size 2**15 in C code, it does not allocate. uint16_t *out = (uint16_t *)malloc(samples_size * sizeof(uint16_t)); if (!out) { fprintf(stderr, "Memory allocation for out failed.\n"); exit(1); }unsigned int samples_size = 1 << 15;Our DTCM 256kb and also ITCM is 256kb.CM7_DTCMCR x 0xE000EF940xE000EF94: 0x00000049CM7_ITCMCR x 0xE000EF900xE000EF90: 0x00000049It seems that I cannot use all 256kb that I have in DTCM.Can you give me insights through this?
Please create a new thread for a new question so others in the community can assist (as well as find answers).
Malloc() will use the heap to allocate memory. Where have you located this (via scatterloading region ARM_LIB_(STACK)HEAP)?
Thank you for your answer, I could not find any documentation regarding this issue, but I created a new thread here:Memory allocation IssueIt would be appreciated if you help me there.Warm regards
